getting a psp and what should be my first game?

I am getting a psp soon and i don't know what game i should get first?

I like shooters and action adventure games. I am thinking about getting resistance retribution or god of war but can you give me some more reccomendations.

This post should go in the recommendations thread :) *cough God of War, Patapon, Prinny Can I Really Be The Hero, Ratchet and Clank, Killzone, cough cough*SlorgieNel

Prinny Can I Really Be The Hero can be very challenging for beginners

It truly goes down to what type of games your into but i would recommend Crisis Core Final Fanatsy 7 best looking game on the system or u could wait for resistance which is gonna push the power of the PSP to its limits
