Just got a PSP from a friend and a few games for really cheap and was wondering what the "must-have" titles for the system are. I don't really care about the genre, a good game is a good game, and on a handheld system with a smaller library beggars can't be choosers. So any recommendations would be good.
Assuming you like basketball... Portable NBA Live or 2k if they have it is pretty nice. I just remember playin NBA Live 06 back when I first got a PSP.. I thought it was pretty good for being handheld. I know they have a few of the GTAs on the PSP.. can't go wrong with that.
Like RPG's? There FF Crisis Core, FF Tactics, and Disgaea (the best time-waster there is). Patapon 2 is a pretty fun, ridiculous game (not an RPG).
I've been playing a lot of Monster Hunter lately, it kind of reminds me of Demon's Souls from PS3. Some people pour over 500 hours into this game. But here's an old compilation from late 08, so you know they could be found for cheap. Beware, huge pic.
