Rev Up Those Sonic Cycles

[Rökkan]

but how will shadow work in terms of "classic shadow"

are they gonna cartoonize him and make him chubby?

Ether they won't bother retrotizing him or they'll make him look somewhat like this:

eugh that's awfully drawn

Don't get your hopes up people, Classic and Modern Sonic are the only ones that will be playable. The other characters will appear for sure, after all, this is trying to sum all the 20 years of the franchise in one game, but don't expect them as playable characters or anything. It'll be cool to see Classic Tails and Classic Knuckles alongside their modern counterparts!
