[MENTION=170]Zero Phoenix[/MENTION]: I think you're talking about PS2 games, the thread starter is looking for PSP games ^^
I'm also a fan of Persona, played Persona 2 on PSOne, finished P3P on my PSP and now waiting for next month's release of Innocent Sin on PSP console.
Thanks for mentioning Growlanser, they also have a PSP release, I think I'm gonna give it a try when I have the chance.
