It is great to have games available for download like this. But, I think the limited capacity of the memory stick duo (the memory card that's used by PSP) will affect this scheme. Question like can we transfer it to multiple PSP not once the game's downloaded occurs to mind. Beside, it would be annoying to transfer games we want to play, and delete the ones on the memory card because there's not enough space left. But I still think that this is a step forward. It's great to have the options even if I might never use it.
