GTA IV got 10 in IGN, and ppl simply say its the best game of '08 so far. Btw, that document is fake.
I'll probably just rent this game, bc I've bought every single GTA before this and I haven't played any of them more than once.
Read some posts here, but some of you don't realise Grand Theft Auto (the whole series) is not based on graphics, but on the feeling. ;-]
