So I'm pretty sure I'm buying a PS3 this weekend and want to get at least one game. I want to get one of the exclusives because I already have an XBox 360. So my options that I'm trying to decide between are Uncharted, Metal Gear Solid 4, Resistance, Killzone 2, or if you can think of any others. I know I can't buy all of them or even two of them. So if I could only choose one exclusive for the PS3 which one would you recommend?
