Mostly running. Not nearly as much stopping as some of the other recent (bad)games. All in all they pretty much got it right here and it pretty much runs smoothly the entire game. Not much story (nothing like sonic adventure) and not so many annoying enemies. A great game!
Actually this is kind of like a compilation of a few levels from all generations of Sonic games, though it includes classic Sonic the hedgehog as an unlockable. If you are looking for classics id recommend Sonic Genesis Collection on PS3 I dont hace it yet but I've read it has all of the genisis classics including Sonic and Knuckles.
