Well, there's the first three Persona games, first two Disgaea games (but you can also get the third Disgaea game and soon the fourth persona game). Final Fantasy V-IX (that's 5-9). There's Final Fantasy Tactics, Dissidia 1 and 2, and a whole lot of others. Just get the PSV and go through the PSP list, it's all there bro!
