Sweet, though why those characters? I've atleast heard of Mighty, but never knew the Squirrel existed. Physical is $10 more than digital so atleast I don't feel bad about not waiting.
Yes Ice Cap is such an amazing level! A crime they failed to include it in both Mania and Generations it is. Also what's so bad about Cream? Not that it would be her, I'd expect fan favorites like Shadow and Blaze.
This is classic Sonic. Classic characters have a better chance than modern ones. Those are for those "fantastic" Sonic team games. xD
