My favorite controller of all time is the Gamecube controller, because it fits in your hand so well and the ABXY button setup is surprisingly natural. I was thinking of getting a GCN-to-PC adapter, but first I want to hear your guys' inputs. Are there any similar controllers I could get instead? Is an adapter the way to go? I already have 3 GCN controllers available.
Also, please don't say "keyboard and mouse," I like it too for most games but when you're trying to play a retro game or platforming there's nothing like a good old controller.
