- The camera, of course
Nope.
- The controls
Not gonna happen.
- Re-do all the game's cutscenes and English voice-overs
They pissed off the old VA's, they won't fix this.
- Update the character models
They have the GCN models, they're going to use those (Except for 2P Default models, those will still be Low-Poly unless they decide to fix that.)
- Make the mini-games like the racing mini-game actually fun (and fix how the cars handle in general so they don't feel like you're driving an ice cube on a ceramic plate)
Why would they fix something if its "authentic to the DC version"
- Fix all the annoying bugs and glitchy-ness of the original game
You cannot be serious.
- Playable Amy Rose (?)
She's in Multiplayer and doesn't serve a purpose other than being a clone of Sonic, why bother?
- Online multiplayer (for the chao races, chao fighting, the racing mini-game, etc.)
I doubt they would go so far as to include something outside of a shitty leaderboard.
- The game gives you character-based themes for your system of choice after unlocking them
How would they accomplish that on the PS3?
I understand that Sega is trying to amend their [tornado fang]-ups with the first Dreamcast batch (Like no Widescreen in Sonic Adventure, Soundtrack for Crazy Taxi completely removed), but they're not going to completely rework the game from the ground up.
