Nerds were waiting by 8pm last night for the midnight release...they're not going to run out of games ya fucking nerds...you might have to wait in line for 30 minutes to get your game at midnight...or you can wait for 4 hours and only wait 5-10 minutes at midnight...not very good at math, eh?

I wasn't a big fan of GTA IV even though I am a Rockstar fanboy. I liked the driving and the physics, but I didn't really like the main story (the two DLC stories that came out were really cool IMO). Also wasn't a big fan of the color scheme, or the map. And I didn't like your friends always calling you, and then if you ignore them (I'm busy, bud) you lower reputation with them.
Also echo the sentiments of Leesin about auto-aim in multiplayer. Same with Red Dead Redemption. It eventually got too difficult to find non-auto aim servers to play in. I don't think that will be as big of a problem with GTA V, at least not with the MP coming out early October, and being fully customizable.
I'm picking up my copy tonight after work, and will not get a chance to play til tomorrow night...going to be a very long 28 hours.
