Sonic: Always Classic

Sonic: Always Classic is the reimagining of the Sonic the Hedgehog series in an alternate universe where Sonic and Robotnik were always the same.

Changes

 * Sonic and Dr. Robotnik were always kept completely identical to their Classic versions. Also, no western/American redesigns!
 * Mobius is still kept.
 * Dr. Robotnik was never Eggman.
 * The western/American redesigns never happened.
 * Tails wasn't redesigned to his Modern look until Sonic Forces.
 * The ages: Sonic and Tails are 8, Amy was always 6 and Knuckles is still 16.
 * The games are changed.

Game Changes

 * The Sonic 3 redesign was rejected, causing it to be cancelled.
 * The other reason Sonic 3 was cancelled because there was already another Sonic 3, from 1993, which kept the Sonic 2 sprites.
 * In Sonic 1, PRESS START BUTTON was always there and stayed there, however the bug was still there, however just the START text was missing instead of the whole message.
 * Hidden Palace is completely kept in Sonic 2, though as an easter egg. This Zone would later become a basic Zone between Mystic Cave and Oil Ocean in both remasters.

Sonic 1
Released: June 23, 1991

Platform: Mega Drive

Development:

Once upon a time, during the start of the 90s (1990), a guy named Yuji Naka was bored and he decided to hire various random SEGA employees to form SEGA-AM8 and make a competitor to Nintendo's Mario. He made a voting for the character, including an armadillo (later became Mighty), a rabbit (known as Feels the Rabbit), a blue hedgehog named Sonic (who was later picked up as the main protagonist) and a fat man in pajamas (later became Dr. Robotnik). The voting ended as Sonic was approved and picked up as the main protagonist, while the fat man became the main antagonist, Dr. Robotnik. Also, they wanted to put Sonic in a band with Sharps the Chicken and various other animals including Vector the Crocodile (who later appeared in Sonic and Tails 3: Sonic Triple Trouble). However, they replaced the band with the SEGA sound. In 1991, the game was released.

Notes:


 * Introduced Sonic and Dr. Robotnik.
 * Remastered for the SEGA Mega CD on May 10, 1993, having Tails, the spindash and the PRESS START BUTTON fixed.
 * Remastered again for iOS and Android in 2013, being the same as the SEGA Mega CD port.

Sonic 2
Released: November 24, 1992

Platform: Mega Drive

Development:

After the success of Sonic 1, SEGA decided to make a better, bigger sequel to the game. They came up with the idea of somebody being the sidekick and best friend of Sonic. That was approved and they came up with a voting where the sidekick is picked, including a turtle (Boomer the Turtle) and a two-tailed fox named Tails. Tails was approved. However, some employees wanted to make a different sequel, which resulted in them creating Sonic CD for the SEGA Mega CD instead. There were various scrapped Zones, including Wood, Rock World, Blue Ocean, Olympus, Dust Hill and the infamous Genocide City (actually renamed to Cyber City because the word "genocide" meaned intentional murder).

Notes:


 * Considered the best game ever.
 * Introduced Tails and Super Sonic.
 * Remastered for the SEGA Mega CD on December 2, 1992, having various bug fixes.
 * Remastered again for iOS and Android in 2013.
