What are the games to have on a 360?
I've been contemplating getting a PS3 for a while now. Originally seemed good because there were a bunch of PS2 games I wanted, so I figured the BC would make it an easy choice. It turns out I'd have to get a PS2 anyway, so now I'm comparing the PS3 with the 360 again (particularly with the cheapest 360 costing half what a PS3 does).
On the PS3 the games I'm really interested in are MGS4 and Little Big Planet (and FFXIII whenever the hell it comes out). They're pretty much flagship titles too. Now I hear that GoW/GoW2 is the one for the 360, but my hands cramp up playing fast paced FPS games (which is the reason I'm interested in MGS4, it can be played much slower).
I wouldn't have thought I'd be into a platformer until LBP, so aside from fast paced shooters and fighting games, I'm open to any suggestions. What are the games on the 360 that might really wow me?
