Sega (Coolot's version)/Sonic the Hedgehog

Sonic the Hedgehog is a very strange 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 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 current voice cast.
 * 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.
 * 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 gaames]
 * The games considered abysmal would never exist.
 * Sonic Boom would be more successful.
 * The games would be more connected with characters and ideas of past games seeping into other games.
