Really? I certainly liked the N64 and Gamecube controllers, but they're not exactly ideal designs for a "universal controller". The wiimote had kind of crappy motion controls and was borderline useless for anything that didn't involve motion. The Wii U uses upgraded wiimotes that suffer the same problem, and the gamepad is more like a giant gameboy than a controller. Plus we can't use any of those controllers on a PC without additional adapters or significant hardware hacks. The Xbox 360 (and to a similar degree Xbox One) controller is designed to be universal, and if you look at what people are using for PC gaming it's pretty much just those two.
