Aye. I've bought Mahjong Tales, Pixeljunk Monsters and Linger In Darkness off the PSN. Decent stuff.. it's just sort of FUCKING LAME they dont let you copy these games to a flash drive or PSP. Although.. technically I cant do jack shit with my PSP besides use it as a storage device.. 'cuz it's got hacked firmware.
Extremely useful PSP, just lacking those cool remote play features that I'd honestly like to use while at work. PS3 games on PSP screen.
