I'm definately in psp are the best much better than my crap DS. i got my psp at christmas and now have
GTA: Liberty City Stories (awesome not a true gta but awesome for a handheld)
Midnight Club Racer: DUB Edition 3 (not bad but not a huge fan of racing games i still played for a long while though)
X-men legends 2: rise of apocolypse (crap at first but when you get into its great)
Pro Evo Soccer 5 (winning eleven i think in us) : AWESOME i played non stop for a week
Ghost in the Shell and Akira : kl but can be hard to watch on the small screen
Green Day:bullet in a Bible - surprisingly funny and graet music of course
i got my DS one year ago next week or something i know have:
mario 64
star wars
All in all psp rocks. DS givs me a warm fuzy feeling inside but has crap games and crap graphics
PSP'S FOREVER
