This is long over due, but I'm finally going to purchase a PSP to play Birth by Sleep. And with Vita coming out the price of the old original model should be fairly cheap everywhere. Any recommendations for some good, old PSP games I should check out? I don't have a PS3 so this might also be a good opportunity to try some of the games only ported to PS3 and PSP like the God of War series. So PSP owners what are some good games you love on the system?
