What are fun games on the psp?? PLEASE ANSWER!!? - picture of ratchet and clank a crank in time

I have a PSP, but I think finding them. I'm not sure if the PSP has a lot of fun games. Can you tell me many games as possible and tell me why the game is fun. I also know that the PSP music, videos, movies, photography and the Internet, but what can he do but call to play.
One, if you know how (the game "Ratchet & Clank: Size Matters, National Treasure 2, (1 GB thing, and something else) What is Chrome, I know I misspelled) and transient and if the game how do you play?
