Yeah, virtual console games are the games you download onto your Wii. The classic controller can be used with all of those games and I am guessing some up coming games such as Smash Brothers Brawl (correct me if I'm wrong).

Though, you're probably better off getting a Gamecube controller if you are planning on getting any Gamecube games, as the classic controller doesn't work with Gamecube games (because they don't pick up blue-tooth devices).

If you couldn't give a stuff about Gamecube games, then just get the classic controller (they are a lot cheaper).
