Pick Starcraft's three PS3 games.

Shit, that's hard. Okay.

1) This would be where I recommend LittleBigPlanet, but you don't seem to like it, so Tools of Destruction.
2) Uncharted 2: Among Thieves. If you like the first Uncharted, you'll probably love this. It has multiplayer!
3) I'm going to cheat and name four. Ratchet and Clank Future: A Crack in Time
4) Heavy Rain. inFamous.

If God of War III releases this year, disregard any one of those games and buy it. It will pwn them all.

EDIT: I would recommend MGS4, but chances are, if you don't own it already, you don't want to.

And seriously look into LittleBigPlanet. It may look crap, and for the first half hour, it is crap, but it gets better, believe me. You could try renting first.
