Cutscenes

Game's Opening

The game's opening begins with Mario and Sonic playing hockey with Luigi and Tails. The four then saw a flyer on the ground that says 'Sports Showdown' on it. Mario, Sonic, Luigi, and Tails ran to their stadiums to start some sports training. In a basketball match between Teams Sonic and Dark, Sonic steals the ball from Shadow and zig-zags passed Rouge and Omega. Tails and Knuckles watched Sonic spin-dash-dunk the ball into the net, making Tails and Knuckles high five. Next in a volleyball match between Teams Rose and Chaotix, Cream and Big toss the ball to Amy and aims it far away from Espio and Vector before Team Rose scored a point. And in a big soccer match between Teams Heroes and Villans, Sonic and Mario passes the ball to Tails then passes it to Luigi who kicks the ball into the goal. Toadette, Toadsworth, Toad, Donkey Kong, Dixie Kong and Diddy Kong are seen playing handball. Toad and Toadette won however when Mario, Sonic, and their friends saw an airship flying above them. Bowser, Dr. Eggman, Bowser Jr, and Metal Sonic jumped down from the Ship along with Zavok, Zazz, Zeena, Master Zik, Dry Bowser, Boo, King Boo, and Dry Bones, challenging Mario, Sonic and their friends to a Dodgeball match. Zavok throws the ball at Amy, hitting her on the head but Blaze caught the ball saving her health bar. Blaze passes the ball to Sonic who's about to release a whirlwind shot and got all the villans out. Just then, Metal Sonic transforms into Metal Overload and challenged Mario, Sonic and co to a big Basketball game. Tails and Amy passes the ball to Vector then to Sonic. Metal Overload blocks Sonic's way to the net. While holding the ball, Sonic transforms into Super Sonic as he fly to the net and dunked the ball, making Metal Sonic turn back to normal. Mario, Sonic and co then celebrated their victory while Mario and Sonic break the forth wall by saying "Let's do this" at the camera before the scene ends.

Sports Showdown Ending

The game's ending plays when the Sports Showdown Emerald Cup is completed in Tournament Mode after beating Metal Overload. It begins with Mario and Sonic entering Mario Stadium for a Basketball tournament at night, with Luigi, Tails, Princess Peach, Amy Rose, Princess Daisy, Blaze the Cat, Shadow the Hedgehog, Silver the Hedgehog and co excited over their arrival. Then Bowser confidently arrives for the basketball rematch, with characters such as Dr. Eggman, Metal Sonic, Wario and Waluigi as his teammates. After everyone gets to their positions, all prepared for the re-match, Peach and Amy passes the ball to Sonic and dribbles the basketball then passes it to Mario makes the dunk. As the ball is dunked in the net, the camera zooms in the ball, revealing the hidden words on it, "SPORTS SHOWDOWN!", then the credits roll.

Story

One day in the Mushroom Kingdom, Toad is gardening flowers when suddenly the sky turns dark, and a strange object falls from the sky and crashes. Toad is worried about the situation, so he, along with some other Toads, rushes to the crashed object to examine it. The Toads find six colored crystals: a red crystal containing a basketball; a green crystal containing a volleyball; a orange one for soccer; a pink one for Handball; a yellow crystal containing a dodgeball; and a blue crystal containing a coin. While observing the mysterious crystals, the Toads suddenly come up with an idea of introducing new sports - Basketball, Handball, Volleyball, Soccer, Dodgeball and Hockey - to the Mushroom Kingdom. The Toads also organize tournaments for the six sports. The best players of the tournament earn a prize: one of the six crystals that fell from the sky. Mario, Sonic, their friends, and their foes are ready to play sports and enter the tournaments to find out who are the best players of the Mushroom Kingdom.

When the players' team wins the Mushroom, Chao, Flower and Spring Cups, and gets to the end of the Star and Emerald Cups, everything seems to be normal. However, in the final round, the Egg Carrier/Bowser's Airship appears and the players' opponent turns out to be Zavok or Dry Bowser in disguise. Zavok/Dry Bowser steals the trophy and jumps onto the Egg Carrier/Bowser's Airship, which prompts the players to follow Zavok/Dry Bowser to get the trophy back. They end up playing against the Deadly team or the Monster Team, while the Egg Carrier/Bowser's Airship flies through space. When the players win against the Team Deadly or Team Monster, they receive one of the crystals that fell from the sky. The leader of the team then uses it to power the Egg Carrier/Bowser's Airship and take the team back home.

After players receive all six crystals, the crystals merge and turn into a dark, glowing crystal. The dark crystal takes the players to the End of the World from Sonic 06. In this area, players encounter the Metal Madness, a boss from Sonic Heroes. The players must defeat the Metal Maddnes before it defeats them. When the players defeat Metal Madness, the dark energy from the dark crystal disappears and turns into a rainbow-colored crystal. The players use the crystal again to power the Egg Carrier/Bowser's Airship to take them back home.

Sports Showdown mode's story is highly identical but the last cup is the Emerald Cup, except after the players' team defeats Team Deadly in the Emerald Cup, the six Sports Showdown trophies that they receive will end up merging into a dark crystal. That crystal also leads them to the End of the World from Sonic 06, where the Metal Overload is found. Similarly with Metal Madness, players have to defeat Metal Overload before it takes them out. When Metal Overload is defeated, the crystal's dark energy disappears, and it turns back into a rainbow crystal. The players use that crystal to power the Egg Carrier to take them back home.

Gameplay

Mario & Sonic Sports Showdown features six playable sports, all unique from each other. Players can play either alone with CPU allies, cooperatively with others up to four players, or against one another. Four players can participate; however, they can participate Co-op mode in Vs. mode since it is impossible to have all four players team up. The Joy Con Grip and Pro Controller control style is used as the primary control scheme for the game. However, the players can also use the Joy Con in the horizontal position. Players are able to perform actions through shaking the Joy Con and/or inputting buttons as shown in horizontal Joy Con scheme. All sports are played in periods, where, except for volleyball there is a certain time limit to each period. When the time limit reaches zero, players move to the next period and change sides. Excluding dodgeball, points acquired in past periods also add up to the current game's total score. In dodgeball, another period commences when all team players get knocked out.

? Panels return from Mario Hoops 3-on-3, where they serve the same purpose: to provide players with either coins, rings or an item. Unlike Mario Hoops 3-on-3, items are held in reserve rather than players holding them. The more coins or rings players have, the more points they can get when they achieve a scoring. Players lose coins or rings when they get hit by an opposing item, which makes the coins and rings scatter on the floor. However, in dodgeball, coins and rings increase the attack power of attacks. Coins and rings increase the power of hitting the ball and players cannot lose coins or rings from items.

There are also special options that can be adjusted for each sport in exhibition mode, such as turning on and off ? Panels, setting the number of periods and the time limit, and other options which can be specific for each sport. Once the options are set, they do not reset whenever a players turns off the game.

On a side note, there's an option which enables the players to receive commands. However, this option is available only when the CPU level is set to "Easy, Normal, Hard, Expert, Pro, or Ace".

Basketball

Basketball is played in a similar fashion as in Mario Hoops 3-on-3. Players must score points by shooting a basketball into their hoop in order to win the game. Whichever team has the most points after all periods wins the match. Two points are acquired when the ball makes it in the hoop; three points are acquired when the ball gets shot from the three pointer and beyond or when a special shot is performed. The coins that the players gather along the way are added to their total score. Also in this sport, which is exclusive to this game, there is a shot clock on the bottom-left hand corner of the screen so the characters can shoot within the time limit, just like in a professional NBA game. If they do not shoot before time runs out, the other team gets possession. Players are also able to defend, block, and make dunks in this game in a similar way to the actual sport. If the score is tied at the end of regulation, then overtime will begin. With overtime in this sport, no game ends in a draw.

Soccer

A sport previously playable in the Mario Strikers series. Unlike that series and as in the actual sport, players participate in 2-vs-2, 3-vs-3 or 4-vs-4 matches.

As in the Mario Strikers games and Mario & Sonic at the Olympic Games Tokyo 2020, the object is to kick the ball into the opponent's goal, overcoming the opposing team members and their goalie, who attempts to block balls, within the designated pseudo 90-minute time limit (the speed of the time limit goes up depending on the settings, but generally speaking, having the highest time setting, 15-minute matches, causes the time limit to slow down). Halfway through the match, at the 45-minute mark, players halt the game and are taken to a screen that records the current progress of both teams. Afterward, the losing team initiates the kick, and the game continues, with the team's goals reversed until the 90-minute mark is reached. Whichever team has the most goals by the end of the match wins the game. Whenever a goal is scored, a replay of the shot is shown. Players can skip the replay if they wish or change the angle from which it is shown. The opposing team captains then get possession of the ball and start off in the middle of the field, beginning the play again.

Unlike in those games, however, players have more control options and strategies available to them to accommodate the actual sport's additional rules. For example, players on the defense can attempt to steal the ball in possession from other players via slide-kicks, pressure defending with their team via the  or by themselves with  (per the default Type A control scheme), or by simply running into the ball. Players who possess the ball may attempt to dodge confrontations by sliding around holding  by default. Powerful Special Shots can be performed by the captain and assistant captain when the ball starts to sparkle. Each Special Shot has a unique visual effect that varies with the character. Team captains may also pass the ball using their Special Combo Shot move to another captain when the ball is glowing as well. All actions are tied to a character's stamina, which is represented by a blue arrow above the controlled character. The more a character plays and dashes across the field, the more stamina is lost. Characters who have a lowered stamina bar have weaker passes, shots, and speed. Players replenish stamina when they do not partake in any action.

Note: There are no fouls, free kicks, throw-ins, corner kicks, goal kicks, nor penalty kicks in this sport.

Volleyball

Volleyball is played by hitting a ball without making it touch the ground. Players first start matches by serving the ball, either by ground or by air. The match then proceeds, while the players try to smack the volleyball so it touches the ground. If that occurs, the last team to successfully hit the ball over the net gains a point. When a point limit is reached (the default is fifteen points), the set is won. Players can spike the ball, deflect a spike, and use many other moves that bear resemblance to the actual game. Volleyball also has an out zone, much like tennis: any player who hits the ball into this zone forfeits a point to the opposing team. Volleyball is the only sport in the game that can never have a time limit.

Dodgeball

A Dodgeball game always begins with a jump-ball that is done by Lakitu to determine which team gets to attack first. Dodgeball is mostly played by throwing a ball to the opposing team. There are two teams of two, three, or four characters and a pink colored Yoshi on one team and a orange on the other team. Players can prevent a hit by catching the ball. Players who fail to catch the ball or dodge it will lose their vitality. They can prevent this if they catch the ball before it hits the ground, especially if the ball flies upwards. Players cannot catch the ball if they are facing away from them, nor can they catch it if an item is in effect.

Players have a Health Meter and lose a portion when they get hit, except for the colored Yoshi, who can never be "knocked out," but cannot leave the box at the back of the court. Players cannot control the Yoshis, unless they encounter the ball, and even then, the only commands that the players can give them is to pass or attack. If players lose all their HP, they are out, and they are sent into their box. However, unlike the Yoshis in the box, they can leave if they damage their target with the ball. Players that do this also get a small amount of their HP regained, but are out immediately if damaged again. However, some alternate route objectives do prevent players who are out from leaving the box; this can also be applied to exhibition matches in the settings.

The first team to knock out the opposing team before the time limit expires wins the set. Additionally, the team who has the most number of remaining players automatically wins when time runs out. If both teams have the same number of players remaining at the end of the time limit, sudden death follows. With this term, no set ends in a draw. In sudden death, the first team to take damage loses the set. On a side note, this is the only sport which has a time limit in which players can set the timer to infinite.

Handball

A Handball game always begins with a jump-ball that is done by Lakitu to determine which team gets to get the ball first. There are two teams of two, three, or four characters and a Blue Paratroopa one team and a Red Paratroopa on the other team. Two teams of two, three, or four players take the field and attempt to score points by putting the game ball into the opposing team's goal. Notable scoring opportunities can occur when attacking players jump into the goal area. For example, an attacking player may catch a pass while launching inside the goal area, and then shoot or pass before touching the floor.

Hockey

A hockey game always begins with a face-off that is done by Lakitu to determine which team will get the puck at the start of the period. If a team scores a goal or a special shot, another face-off will take place. The goalkeepers in this sport are Shy Guys, and their color depends on which team they are in. In order to steal the puck, players must tackle each other, which can be achieved by the motion of shaking the  ( in sideways mode) or simply by making a character go in front of the opponent with the puck. Sometimes, a struggle ensues and players must shake their Wii Remote the fastest that they can in order to win the puck over and knock the opponents away. The team with the most points wins and, very much like basketball, this game is played in time limits and transitional periods. This sport uses a Hockey Stick.

Sports Showdown

Sports Showdown is a tournament-only game mode, which uses all of the sports. To unlock it, players must complete all six Star and Emerald Cups and defeat Metal Madness. In this game mode, the sport that is played is chosen randomly for each round. Computer controlled characters are set on Easy, Normal, Hard or Expert difficulty levels, When the players beat the Star and Emerald Cups, they fight the Metal Overload instead of Metal Madness. Metal Overload has more health than Metal Madness and is harder to beat.

Players can select only characters and costumes that are unlocked in all six sports. For example on a similar manner, recolors cannot be used unless they are unlocked for all six sports as well.

Characters

Playable characters

There are thirty-nine playable characters in Mario & Sonic Sports Showodwn; everyone are default. All of them are categorized by four groups:

  • All-around - All-around characters have average Power, Speed, and Technique. They generally are not weak at any stats, but they are not strong in any either.
  • Technical - Technical characters have more Technique, but less Speed and Power. These characters can better aim their shots.
  • Powerful - Powerful characters have more Power, but less Speed and Technique. These characters have stronger and faster attacks and shots.
  • Speedy - Speedy characters have more Speed, but less Power and Technique. These characters can move faster over the ground.

As Mario Hoops 3-on-3, this game is shown to make use of character specific abilities. Prior to using these abilities, there is a meter that needs to be filled (shown on the bottom left and right corners of the gameplay screen). These abilities in question can allow the characters to unleash a powerful move in the variety of sports in the game that can help the players win a game. Each special ability is unique to each character and these moves tend to vary from the sport that players are playing.

Finally, the playable characters have their own stat values, which depict their strengths and weaknesses. For the respective charts shown below on this article, the stat values for each playable character are out of 5.

Zavok, Zazz, Master Zik, and Zeena appear as non playable CPU opponents for the Emerald Cup finals and Dry Bowser, Dry Bones, Boo, and King Boo appear as non playable CPU oppenents for the Star Cup finals. However, they can appear when players are taking alternate routes.

Alternate colors and outfits

Certain characters have alternate colors that can be unlocked by performing certain objectives. Alternate colors can be used only in the sports that they are unlocked in. To scroll through colors, the players can press the + button on the Joy Con, regardless of the control scheme used.

In tournaments, it is possible for the CPU team to use more than one of a certain character, which is now possible for the players' team, and in exhibition matches. Likewise, if the players' team contains a character who has an alternate color, the CPU team can still use that character's unused colors in tournaments; for example, if the players' team contains Yoshi, it is still possible to see a different color Yoshi in a CPU team. CPUs can use alternate colors of characters even if the player has not unlocked them yet.

Items

As in most Mario and Sonic games, there are items available during the gameplay of Mario & Sonic Sports Showdown. These items are available by touching the available and various ? Panels on the court. Most of these items can struck players to make them lose coins, and all items also affect teammates as well.

Item Name Function
160px-Spiny Shell - Mario Kart Wii.png
Spiny Shell The Spiny Shell appears in many Mario Kart games as an item from an Item Box. But now it appears in Mario & Sonic Sports Showdown that'll hit any oppenent.
100px-Banana - Mario Kart Wii.png
Banana A single banana is thrown into the court. The bananas can make players slip and fall, which stuns them for a brief amount of time. Bananas can also be used to block incoming shells. When players use the item in conjunction with the ball/puck, the ball/puck makes a homing, wide curve and can hit anyone with the same effects of a banana.
Bob Omb.png
Bob-omb A bob-omb is thrown correspondingly to the user's aim. When the bomb lands, it explodes, knocking any player caught in the blast radius. Bob-ombs also obliterate items in its radius. A mini-game, Bob-omb Dodge, has a sole purpose of tossing Bob-ombs of various sizes at players, who must dodge these bombs.
90px-NSMBDS Coin Artwork.png
Coin Though not an offensive weapon, unlike all other items listed, coins play a vital role in Mario & Sonic Sports Showdown and serve as a puck in hockey, although the latter role is not associated with its sole purpose. Coins are mainly collected by running on ? Panels, but are also obtainable by stage hazards or by stealing them from other players via offensive items. Coins increase the score output and how much damage is done to players in dodgeball. Coins get depleted into points once players score or hurt players in dodgeball, which means that players must collect coins again if they want to score more points. A maximum of 10 coins can be collected at a time.
Ring SatSR.png
Ring Same thing like the coins.
100px-Green Shell Artwork - Mario Kart Wii.png
Green Shell Similar to its function in the Mario Kart series, Green Shells move in a straight line and bounce off any wall. They get destroyed by any other item in play and disappear when they hit another player or bounce in the wall enough times. When used in conjunction with the ball/puck, this item homes towards its goal and can hit any player in its way, however stopping the ball/puck momentum.
Speed Shoes (Sonic Lost World Wii U).png
Sneaker The Sneaker makes the player run super fast for 15 seconds.
100px-Mini Shroom.png
Mini Mushroom The Mini Mushroom shrinks any players it comes in contact with. Except when used in conjunction with the ball/puck, the Mini Mushroom behaves quite similarly to the Banana; they both get lobbed and both remain in one spot. Any player turned mini cannot perform most moves and gets movement lowered. The Mini Mushroom's effects revert over time.
100px-MKW Red Shell Artwork.png
Red Shell Much like the Green Shell, the Red Shell functions not too different than its counterpart in the Mario Kart series. The Red Shell homes after its nearby opponent. When contact is initiated, the player gets knocked in the same manner as a Green Shell. Red Shells do not rebound off walls and can get destroyed by another item. When used in conjunction with the ball/puck, the Red Shell does a large curve and homes for the goal. When in this form, the Red Shell can knock other players away, but this stops the momentum of the ball/puck, much like the Green Shell.
100px-Star.png
Super Star Not too different than its functions in other various games, the Super Star makes players invincible. Unlike all other items, this item can be obtained very rarely, most likely to the losing team. When this item is collected, it automatically activates itself. The Super Star not only makes players invincible, it also powers up the ball/puck, making it impervious to other player attacks while flying through the players, homing to the goal and moving at a much faster speed.
SFSBShield.png
Shield The shield protects the player from items, hazards, and special shots.

In the Metal Madness/Metal Overload battle, players can also collect Meteorites from ? Panels. Meteorites can be used in different ways; they can be thrown at Metal Madness/Metal Overload to damage it (like in Dodgeball and Handball). Players can also "dunk" it at Metal Madness/Metal Overload (like in Basketball), or kick it (like in soccer). They can also pass the Meteorite at another teammate. Players must receive it and pass it to another player (Volleyball). By doing this, the SP Bar fills marginally, and the meteorite gains power. Coins and rings can also be collected from ? Panels to give it more power. When the SP Bar is full, and all the players of the team are still in the game, the players can use a Special Shot. This can give Metal Madness/Metal Overload significant damage. When the meteorite falls on the ground, it and its power disappears; players must collect a new meteorite and recharge it.

Modes of play

"Mario & Sonic Sports Showdown has two game modes for each one of the six sports: Exhibition and Tournament. Each sport also has a tutorial video so that players can learn how to play these sports."

— Omochao

Exhibition

Players can select which court to play during a dodgeball match in Exhibition mode.

Before a match starts, a VS screen will be shown to let players know which two teams are involved.

Exhibition mode allows players to play any one of the six sports and customize the rules of the match from the court selection screen at anytime before the match begins (see Gameplay for more info). From there, players can select any four, six or eight of the thirty-nine playable characters and one of the twenty compatible courts.

Character skins can be unlocked by playing with a particular character certain times. This also counts for Tournament mode. However, what players unlock can only be used in that sport.

Tournament

In Tournament mode, players can compete for the trophy in the same manner as in Mario Hoops 3-on-3. There are three rounds in the tournament. When players win a game, they move on to the next round of the tournament. Each time players win a cup, they can earn one of the three small crystals that corresponds to the sport's color and the players moves on to the next tournament. If all six cups are cleared for that corresponding sport, then it becomes a Sports Crystal that is placed on the Egg Carrier/Bowser's Airship.

After winning the Star and Emerald Cups of a sport, players unlock a Hard mode for that sport. Opponents are more difficult than in Normal mode. Also, if players clear the Star and Emerald Cups at all sports, they receive all six Sports Crystals to power the Egg Carrier/Bowser's Airship. After collecting all six large crystals, they battle Metal Madness and defeat Metal Madness. Sports Showdown mode is unlocked when this is cleared. Sports Showdown has four skill level options, which are Easy, Normal, Hard, and Expert, and it is a tournament in which each match is a randomly generated sport. Also, clearing the Emerald Cup in Sports Showodwn mode makes players face off against the Metal Overload.

Difficulty Descriptions

Easy: "Rookie oppenents can let the players win super easy and the oppenents won't score points."

Normal: "Enjoy a standard tournament as you take on increasingly difficult opponents in each round!"

Hard: "Test your skills in a more challenging tournament against advanced opponents."

Expert: "Now your opponents are getting serious! The sport changes with each round, so get ready!"

Alternate routes

Players can also replay tournaments to find alternate routes, but they must clear the tournament the first time in order to do so. Players can take the alternate route once completing the first round. Then, in the second round, arrows will appear. One arrow will take the players to the alternate route, while the other will keep them on the normal route.

In the alternate routes, players do not play normal matches, but missions instead. If players lose a mission, they get sent back to the normal tournament. If players win a mission, they may continue on, but the road often splits. Players may choose which way they want to go. These roads lead players to different missions, different events, or sometimes even back to the normal tournament. Once players come back to the normal tournament, they cannot re-enter the alternate routes until they start over the tournament.

Taking right choices or guesses, players may reach the Hidden Final. The Hidden Final is the last mission of the tournament. If players lose this mission, they do not get sent back to the normal tournament, but they can retry the mission instead. If players win this mission, they earn the tournament cup, just like players do in the normal run. The Hidden Final involves completing a task that is usually more difficult than the others, for example, winning a match without allowing the opponent to score even once.

Players may unlock hidden character skins by winning missions. However what they unlock depends on the mission, the sport, and even the routes they took before reaching the mission. Unlocked items are only accessible in the sport players win the mission in.

Alternate routes in the Star and Emerald Cups are slightly different compared to the Mushroom, Chao, Flower and Spring Cups. If players win some missions in the route, they can travel to the Star and Emerald Roads. If players manage to reach the end of the Star or Emerald Roads, they get a message Star Road Complete or Emerald Road Complete!, and travel back to the normal tournament by jumping on the Star.

Unlike the Mushroom and Chao Cups and the Flower and Spring Cups, there is no Hidden Final for the Star and Emerald Cups. Instead, after clearing the Star or Emerald Road, players immediately go up against Team Deadly or Team Monster. Unlike with the normal tournament, however, crystals do pop up during the match; the crystals act like coins and rings, which add extra points for Basketball, Soccer, Volleyball, Handball, and Hockey, while strengthening attacks in Dodgeball.

Graphical changes

When completing sports in Tournament mode, some items in menus of the game change.

  • Once a sport is completed in Normal mode, a crystal marks the sport in the record menu. When the sport is completed in Hard mode, the ball (or in case of Hockey, the stick since the coin is already gold) turns gold in the main menu.
  • If Sports Showdown mode is cleared, the usual blue background of the main menu turns into a gold-red colored background.

The effects of the background changing to a goldish-red and the effects of the ball (or stick in hockey) and unlocking everything are also used if a cheat code is performed.

Party games

In addition to the tournament and the exhibition modes, Mario & Sonic Sports Showdown has six party games, one for each sport. They can be played for up to four players.

All Party games have at least two levels.

Record book

The game does keep track of the player's records for each sport. The records basically go as follows:

Reception

Reviews
Release Reviewer, Publication Score Comment
Nintendo Switch Alex Navarro, Giant Bomb 2/5 "Mario & Sonic Sports Showdown simply comes across like a bizarre copy of a copy. It's a fax-machine quality retread of such startling inanity that, at a point, you might actually find your fond memories of Mario and Sonic sports games past overwritten by this blur of dispassionate mediocrity. We're a long way from the days of great games like Mario and Sonic Baseball and Mario & Sonic Golf: Resort Tour, and with each progressively lamer franchise installment Nintendo and Sega thrusts upon us, that divide just continues to widen.'"
Nintendo Switch Keza MacDonald, Eurogamer 7/10 "As a whole package, this isn't quite up to the standard you'd hope for from Mario Sports, but it certainly doesn't damage the series' reputation."
Nintendo Switch Peter Willington, Cubed3 7/10 "Mario & Sonic Sports Showdown is a solid title but by no means is it astounding. It lacks the focus or complexity of a Toadstool Tournament or Power Tennis, opting instead for a more casual focused crowd that want a bit more than Wii Sports Resort can offer. Fun? Yes. Lasting fun? Not so much."
