With the good amount of promotion that's gone into these two characters would it be a good idea if the next Sonic game only featured Sonic, Shadow and Metal Sonic as playable characters?
In the 3D Sonic games we've seen that Sega have had difficulty with implementing some of the supporting characters into a 3D arena and retaining a traditional Sonic gameplay experience. Not to say that they should give up, I'd definitely like to see Espio, Vector, Tails and the others return to 3D Sonic platofmers, but for now maybe a new approach by concentrating on the fast characters?
There'd still be PLENTY of room for differentiating the abilities of the characters.
Sonic would be the most athletic, being able to interact with scenery in ways Shadow and Metal Sonic don't have the ability to. Grinding, grabbing, swinging etc. If there are any power-ups in the game they could grant Sonic extra abilities that they don't other characters (like the shields in Sonic 3 & Knuckles). Sonic could also be able to use his speed to produce wind vortexes and similar attacks, be ale to skim across water surfaces like a stone (see both Sonic & Tails games on Game Gear, aka Sonic Chaos and Sonic Triple Trouble) and perhaps the fact that he's the only character out of the three whose feet actually touch the ground when he's running fast could have useful effects on certain ground surfaces.
Shadow would be able to pick up and use weapons dropped by robot enemies, have some limited hovering abilities and plenty of energy attacks.
Metal Sonic would have the fastest acceleration, some limited flying abilities, a limited shield (see SA2B) and a laser attack. He could also have the ability to interact with computerised elements of stages, opening electronically locked doors, deactivating alarm systems etc.
Metal Sonic would be in his sleek classic look of course, maybe with the ability to transform into his Sonic Heroes look (the one we didn't get to actually fight) in some of the later boss battles.
With these three playable characters the theme would be similar to Sonic Adventure 2, you'd be able to play as a hero (Sonic), anti-hero (Shadow) or villain (Metal Sonic).
And better yet, since as of Sonic Heroes, Metal Sonic no longer works for Eggman, so Eggman and his robots could be the main villains of the game again. No more getting betrayed by powerful sidekicks or being a mere sideline villain, Eggman could be the number one baddie again.
The usual final chapter could be expected after completing the game with all three characters of course, but let's not have Metal Sonic teaming up with anyone, especially not Sonic, as that would undermine his character (and besides, we've had way too much "bad guy turned good or forced to work with the heroes" in the series already).
