Before, I was more leniant towards the PSP, but after a while, I grew to like the DS more after I got a modchip. The PSP can no longer play homebrew games after being updated past 2.00+, i believe, as for the DS, it always has that function. Some of the homebrews can outdo the PSP, no less. For example, someone converted RPG Maker XP into DS format, and I've seen it played. I think the DS should get more credit that what it's been given.
