What are some good PSP games?

So Kelsey was cleaning her room and guess what she found??? Her dusty PSP, the one she hasn't touched since like 2007. LOL the most newest game i found in there was NBA 07. I'm really nor into games like that no more. LOL my PSP is sooooo old! I got it Christmas `05!!! 8th grade hahaha I'm about to be a senior!
