Sega (Coolot's version)/Sonic the Hedgehog

Sonic the Hedgehog is a very strange and peculiar franchise, so I decided to do my own take on the franchise, starting all the way at pre-Adventure era.

Changes

 * The games' setting is always referred to as Mobius.
 * The games keep the Zones gimmick.
 * The core cast would still consist of Sonic the Hedgehog, Miles "Tails" Prower, Knuckles the Echidna and Amy Rose, although with some tweaks to their personalities.
 * Tails is slightly aged up, although still younger than the others, as he shows more TBD.
 * Amy is rather more mature since she would act more professional towards Sonic and she would be more protective towards her friends.
 * Likely as a direct result, Cindy Robinson's voice for Amy sounds more like how she sounds on Boom and more recent installments rather than the higher-pitched voice from the earlier games with the Studiopolis voice cast.
 * A few ages are slightly tweaked: Tails is 12, Amy is 14, Cream and Marine are both 11 and Silver is 15.
 * Sonic X-Treme would have never been cancelled as Gazebo and /Tiara Boobowski/ would become recurring Sonic characters.
 * Sonic SatAM and its Archie sequel would still set apart from the game canon, although it borrows elements from the canon.
 * The reboot would never happen as Sega and Archie Comics avoided the lawsuit that triggered it by paying royalties to the characters' creators in order to keep them under Sega's ownership.
 * Silver, Blaze and Marine would be introduced in Sonic Heroes as an additional team.
 * Shadow and the Deadly Six wouldn't be overused.
 * [not using Classic Sonic in mainstream games]
 * The games considered abysmal would never exist.
 * Wii/Wii U exclusive games would also be released for PC, PlayStation 3, PlayStation 4, Xbox 360 and Xbox One.
 * Sonic Boom would be more successful.
 * The games would be more connected with characters and ideas of past games seeping into other games.
