I'd be wiling to play more badly-reviewed games if they all had demos that I could try out; sure, XBLA's great for that, but the demos for the 360 games take up almost half of my remaining disk space each, and take an hour to load. And the Wii doesn't have any at all; what happened to demo discs?
This may be a slight tangent, but I don't see why all of these classic game companies don't just dump their entire backlog onto the VC/XBLA/PSN channels; this staggered release business is ridiculous, because the years of lost sales for releasing something 3 years after the service began has to outweigh any benefits to releasing them one at a time. I was planning on getting Super Mario Kart & Star Fox on the VC, but instead I got them and an SNES system used (which I don't consider wrong since the company already got paid for them, and the previous owner doesn't get to keep a copy.
