I'm really on the fence with this thing. One one hand, it's pretty nifty for sure. On the other hand, it's just emulating the hardware...so why not just emulate it on a PC? I mean, I could order a couple of the USB controllers and play it on my HDTV just as easily as with the Neo Geo X...and I would still have blood, save features, etc.
It's cool, but I honestly don't see myself picking one up after seeing what it does.
