I really liked the GTA games. I admit I'm a Grand Theft Auto fan but there are very kool on PSP. I have also a modded PSP so I can download games :$.
I have 3 PSPs, none are moded. I feel like a normal person who wants more games...
Anyways Buy:
Resistance Retribution
Syphon Filter: Dark Mirror
Syphon Filter: Logan's Shadow
LocoRoco
LocoRoco 2
Patapon
Tekken: Dark Ressurection
Jeanne D'arc
Final Fantasy Tactics: War Of The Lions
God Of War: Chains Of Olympus
Ratchet & Clank: Size Matters
Daxter
Secret Agent Clank
I can continue...
I could do with getting some more games for PSP I only have Sonic Rivals 1 & 2 and Burnout. But there's just no good one's.
resistance retribution is a great psp game, kind of a copy off gears of war
