I bitch and moan about modern games and their lack of ...well anything, but I am completely amazed with this game. I enjoyed the hell out of GTAIII, vice city was fun, san andreas brought some cool concepts, but I believe GTAIV finally nails the series on the head. It's like playing in a movie. The story is engaging and the Niko the anti-hero is one of the best characters to come around in a long time. Is the game perfect? Not by a long shot, but it's just so damn fun and the tongue 'n cheek humor is still there.
Although I thought I was the only one that had made this assumption a while ago, a lot of others have thought the same thing...
