New Super Mario World

New Super Mario World is a 2023 Mario game developed by Nintendo. It is the sixth game in the New Super Mario Bros series, and features several new mechanics that set it apart from the rest. It is the first mainline New Super Mario game where Miis are playable. The game was received positively by critics and considered to be one of the best in the series.

Story
Bowser has kidnapped hundreds of Toads from the Mushroom Kingdom and is using them to build his kingdom. He teams up with his long-lost brother, who first appeared in Super Mario Bros: The Lost Levels. Together they kidnapped Peach and Daisy, and Mario and Luigi have to rescue them and save the Toads, who are being held captive in various locations across the Mushroom Kingdom. Mario eventually reaches Bowser's castle and fights him and his brother, who are both eventually defeated. The Toads are freed and Mario rides home in a clown car with Peach.

Gameplay
New Super Mario World has several mechanics that make it the most unique game in the series. Each level has at least one exit, which contains a Toad being held captive. When Mario rescues enough Toads in a world, the next world opens up. The worlds are much larger than normal, with both Towers and Castles, and sometimes Airships. There are 150 different levels, and some will open up in an earlier world when you are later in the game. For example, World 1-7 opens up after completing 3-4. The core gameplay is roughly the same as previous entries, however there are new power-ups and enemies. There are 8 worlds in total. World 8 can only be unlocked after the Castle is completed in each world up to that point. Yoshi also returns in some levels.

Rescuing enough Toads can open up various buildings throughout the worlds. This includes item houses, 1-up houses, and warp cannons. An entire world called Toad Town is available after clearing World 1.

Power-ups
New Super Mario World has a total of 10 power-ups, excluding Super Mushrooms and Super Stars. The returning power-ups are:


 * Fire Flower
 * Ice Flower
 * Propellor Mushroom
 * Penguin Suit
 * Mini Mushroom
 * Boomerang Flower
 * Super Acorn

The new power-ups are:

Water Flower
Shoots a water ball that travels far but doesn't bounce. Most regular enemies (Goombas, Koopas, etc.) cannot be defeated by it, but are instead stunned for .75 seconds. However, It can vaporize magic balls from the Koopalings, Bowser and Bowser Jr's fireballs, Lava Bubbles, and fireballs shot by any enemy. It can also harden Lava into stone that can be walked on for a few seconds.

Phoenix Suit
This lets Mario fly and shoot fireballs. The flight is similar to the Wing power-up in Kirby's Return to Dream Land, but with a limit. It can be used to reach higher areas. It also shoots fireballs, making it a fire counterpart to the Penguin Suit. It appears commonly in World 8.

Gold Mushroom
The Gold Mushroom originated in the Mario Kart series, and appears as a rare power-up here. It is functionally similar to the Superball Flower from Super Mario Land, and the Gold Flower from New Super Mario Bros 2. It allows Mario to shoot up to two golden balls at once that ricochet off walls and explode after hitting enough walls or an enemy. This power-up is one of the rarest, but also highly powerful, as it can defeat a cluster of enemies or send a Koopaling into its shell with one hit.

Worlds
New Super Mario World contains eight expansive worlds which each have a theme. Unlike previous New Super Mario games, the world themes are more broad and contain multiple level types. For example, World 7, the Sky, also has Mountain levels. The worlds are:
