How about Final Fantasy 7 if it's available in your country. Call of Duty: Roads to Victory was a nice game in my PSP. Fifa 10 is like to be the nicest sport game in PSP. Twisted-Metal was the least nice game. Sonic Rivals 1 and 2 are like to be the nicest third perspective game in my PSP. Final Fantasy: Dissidia game was good cause you just had a war between good and evil. but hey, I didn't try this game.
