What Game Should I Get?

I just got a ps3, but I have no games. However, i'm going this weekend to buy some. Which games should I get?  Im already going to buy DBZ: Raging Blast, Dragon Age, Tekken 6, and Little Big Planet. what else should i get?

Really, DBZ raging blast? 
 
Also Get Modern Warfare 2.

InFamous maybe ?

Raging Blast looks sooo awesome. I love the tenkaichi series and this looks to make it even better! I'd say get inFamous, as well as Demon's Souls if you're up for it.

 Metal Gear Solid 4  yeah
