1. Costumes for every playable character.
- It would be cool to have the option to dress the characters up as their Classic or even Boom self or even play as other characters that have similar move sets. For instance Sonic can have costumes that let you Play as Shadow, Amy, or Metal Sonic while Tails could have one that lets you play as Cream, Knuckles could have one that lets you play as Rouge or Tikal, or Amy could have one where you play as Sonic with Caliburn. Another thing that can be done is having one off variants of the characters be costumes like Tails as Ali Baba from Secret Rings or Knuckles as Sir Gawain from Black Knight or even Possessed Amy from Sonic X.
2. An expanded Mission Mode from the Directors Cut.
- Simple as it sounds include a new take on the Mission Mode but make it so every character has an equal number of missions.
3.A version of every stage for every character.
- Once again another simple one after either beating their story or even Perfect Chaos unlock a version of every stage made for every character in their own gameplay style.
4. Include the Dreamcast original as a bonus unlock like the Medievil remake did.
- Once again another simple request just have it as an option on the title screen after get all the Emblems and be sure to include the original system boot up like the Medievil remake did.
5. Either the complete removal of the chao garden or have it completely separated from main game progression.
- Now I know a lot of people like it but I don't it just takes to long for the chao to level up anything and grow up and get to the point you can do the races to get the Emblems. If it must still be in the game just have nothing but chao garden stuff be locked behind winning races and make it so their are options to speed up raising the chao. I don't want to waste hours raising a chao just to unlock costumes or even the Dreamcast original like I had to do to get Metal Sonic in the DX port or Green Hill in Sonic Adventure 2 Battle.
