Judging by him playing in the video, if they can make that scroll-wheel smoother, it may play rather well - he glitched a bit, but it seemed to generally go in the direction he wanted. As for the screen size, don't forget today's dot pitches. And it's not much smaller than if you were to play Centipede in portrait on the Pandora's landscape screen - or maybe it's actually bigger. I personally hope this thing ends up being hackable to put more roms on it. I love the Centipede side art (as you can tell from my current avatar) but in practice I'd just as well enjoy a game of Missile Command. Then the could make units with 4-way (Lode Runner) and 8-way (Gradius) controllers (not sure how at that scale and making it still usable though), and maybe a spinner for Tempest and I'd be sorted.
