I have been screaming for a Bionic Commando game for years. It's one of my favorites from the NES days. I think it would work best on the DS or PSP. It needs to be a side-scroller and doing 2D would keep Capcom's costs down. Personally, I hope it would be on the DS because I don't own a PSP. But I would buy one if Bionic Commando released on it.
