You can change the control options from Standard(GTA4) to Classic(GTA3, Vice City and San Andreas) in the options.
So far the game is great but some of the concepts it looks like they stole from Saints Row and the Graphics and Gameplay is a lot like Saints Row too.
Either way it's a great game I think I'm @ 23% completion.
Anybody played the Multiplayer yet?
Also the control scheme is all screwed up. It's totally different from all the previous GTA titles which kinda sucks. It's taking a lot of getting used to
So far I give it a 9.4/10
I still think San Andreas is the best of the 4
