Amazing graphics, amazing story, amazing gameplay... what more is there to say!?!?!? GTA4 almost beats San Andreas!!!!!!
The graphics are the **** and they make San Andreas look like **** but San Andreas had better environments and more fun vehicles and **** to screw around in. Overall it is very hard to say which is the better game, but San Andreas in its time was just a little bit more better.
But GTA4 is still a game that you will be playing forever cause there's so much **** to do and once you have 100% of the game complete you can just rampage and go ape-**** on everyone and everything, it's so **** cool.
So if you don't have this game, get it. If you don't like this game, suck it. Rock on RockStar!!!
