I have been playing mine since yesterday.
This thing is ****ing SICK!
I have Uncharted, ModNation, Little Deviants, and Escape Plan.
Uncharted is amazing. I sit there with this handheld system playing something that looks like it belongs on my TV. I can't stress how great playing this game is.
Modnation is great and plays much better than the PSP version with the analog stick instead of the nub.
Escape Plan I haven't got much time into yet but the music and style is awesome.
I get how some people dislike the price but this is the REAL DEAL when you think of wanting to play your full size console games on a handheld. I think at $250 it's a good deal. Just my opinion.
