Can anyone tell me which games they think are the best for the PSP? My favourites are RPGs, puzzle games, adventures and platforms, but any other game with an interesting concept and/or fun enough will be gladly taken into consideration. This includes homebrew software and games you can emulate on a PSP (but please add a tutorial. I would love to know more about emulation on PSP). I was thinking about getting Parappa The Rapper... is it worth it?
