psp is freakin awesome, I just picked one up and I love it. I've got Capcom classics and thats great playing old school games. I want to get the midway classics so I can play 720, and paperboy.
Tiger Woods is great for PSP too. Can I tell you how handy a PSP comes in handy on a flight? and the monster grips are a must for big hands, plus extra battery life. it feels like playing with a ps2 controler but the screen is in the controler.
