which game should i buy?

I would suggest you get Gears of War 2 it's going to be the next big game but it doesnt come out until November (not sure on the exact date)....My second suggestion is CoD4 Since it is a pretty good game....Last Suggestion if you don't have Halo 3 you should Definelty get it in my opinion it's a Great Game.

gears 2 comes out November 11. I would Get That Definately.

but only if you have played Gears 1. b/c you may or may not like it.

and then i would get CoD:World at War, it Seems like it's gonna be great, and GTA IV is like all the other GTA's, its fun for a few weeks, but the missions are repetitive and it gets boring.

The "wargame's" are pretty much the better deal, b/c of ONLiNE. But then again....if you dont have Online i would Get GTA IV.

I'd probably go with Gta 4, If I had to choose only one. simple because you cant go wrong, single player is long yet enjoyable, online is great.

Cod 4, is cool dont get me wrong, but the single player mode is a bit short, if you're really into online and want a war game then this should be it

saints row 2 is fun, really fun, but gta 4 is the better of the two by far, i'd wait for the price to go down before even considering buying it "rented it"

gears of war 2, who knows, it's suppose to be huge, maybe you should wait for some reviews.

is cod5 even out yet?

all in all, If I had to choose one, I'd go with gta iv, it will keep you busy long after you beat it.

I have COD 4. Can't wait for COD: World at War. My favorites are COD4,(Game of the Year Edition) Halo 3, Army of Two, and I can't wait for Halo 3: Recon, Halo 3 Mythic Maps, and Halo 4. Halo 4 is going 2 be like Doom.(Pop out and scare you)

Call of Duty 4! It's the best game on the market in terms of action and real combat. Call of Duty 5 won't even replace it, the game is that cool!

Gran Turismo! Oh no wait this for xbox nevermind
