New Game Suggestions?

Hello,

 I am going on a long trip soon and want to know what a good PSP game would be for me to buy.  I have looked into SOCOM 2 and am curious about what the control scheme is.  Also, are there any simply great games that i should get.

 I own: (GTA:NYC,Burnout Legends, Fifa 06, X-men Legends)

Thanks 

I love Daxter, if you like jump&runs, you have to buy this great game. I think it's a little bit to short, but it makes a lot of fun. BadNero

Daxter is cool and is a must have game for the PSP.
