i got a psp on impulse last week. i already have a pc, xbox360 and ds amongst others. i aint a fanboy of any system. the games i have, and my initial thoughts are:
loco roco: its unique - very good
wipeout: its wipeout, enough said - very good
star wars battlefront 2: average / poor - i guess the psp doesnt do fps very well?
ridge racer 2: average - i guess the psp doesnt do racing games (non wipeout) very well?
i only heard good things about kill zone. think that will be my next buy.
any other recommendations?
