you must have a PSP for it as it only comes on UMD, it's the reason i baught a PSP, i actualy pre-ordered the game months before i had a PSP... don't get the PSPgo as it is overpriced and a downgrade of the PSP 2000/3000 with a smaller screen, cramped controls, and a palm cramp inducing design (even for someone with small hands), and it uses a totaly different memory stick than the original PSPs... it's only saving grace is a large HDD and BlueTooth which are hardly necessary unless you wanna play download only games, i would suggest finding a PSP2000 as the 3000 has scanline issues though the colors are brighter by a small bit...
