The Virtual Console on the Wii is a great idea and I have taken advantage of it. The games on the old Nintendo systems, the Genesis, the TurboGrafx-16, and now the Neo-Geo almost makes the Wii purchase necessary by themselves. It could be more, though.
I think that the VC should be a one stop shop for all kinds of old-school games that many people have never had a chance to experience before or just can't play them on the old systems due to the age of the systems, cost, repair, etc. I think the VC should offer games from the Atari systems (2600, 5200, 7800, Jaguar), Colecovision, Intellivision, 3DO, Magnavox Odyssey, etc. With all the different controllers out there and the ones that Nintendo is currently producing, special retro controllers could be made available for these types of games. An all in one system with a library of classic games all across the spectrum of gaming history. That's what I want.
