getting a ps3...first game?

I want to play Uncharted 2 and GoW3 but...I've never played any other games in either series! So I'm thinking U1 or the GoW collection? I'm just worried neither is a great "show off the system" game...(although I guess I could just get demos to do that?)

UC1 and the GOW Collection are good starts. I also gotta recommend Demon's Souls, though.

Ohhh yeah I def want Demon's Souls too.
