What is your fave game in psp pls. give a review from a great web site?

pls with review from sites like gamepro (but not necessarily game pro.) review of game

I would say AVPR for psp but havent played it they say it's alot of fun. Twisted Metal Head On is probably one of the funnest games and works really good with the psp- controls, graphics, multiple storylines. Gampro, PLaystation.com, or www.ign.com is a good sight for these two games review.
If I could I would make a game for the psp that plays like the Original Doom games- easy shooting for psp. And make it a fun scary game with locked doors and puzzels like doom and intense weapons and 12 player multiplayer with 4 player coop.
