If he's a casual player, he'd probably be better off with a DS. But if he's got his heart set on a PSP, it would probably be better if he just bought a normal PSP; they can hold data with the memory cards and play physical copies as well. Also, Sony added a whole bunch of "casual" minigames through the store called "miniz", but I've never felt inclined to buy any of them. Then again, they're relatively cheap, and your friend might appreciate them.
