best psp games ever played?  

god of war.
diner dash (nyahahahah!)
naruto

For me, crisis core is one of the best games I've ever played. But nothing beats patapon when it comes to gameplay. The graphics may be simple, but it beats most games when it comes to gameplay. You should try it. I like naruto too, still waiting for the second installment.

For me, the best game I ever played in PSP yet are the Monster Hunter Series. It's just so cool to hunt monster downs using some clever strategies and cool unique armors and weapons.
