[quote name='cheapasssmurf']What about super monkey balls?[/QUOTE]
Yeah, no kidding, DO NOT give that game to a non-gamer, they will throw their Wiimote through the TV in frustration. Hell, I rented it, breezed through the first few levels, struggled a bit with the next 2, and then came to a screeching halt - could NOT complete a few of them on the 5th or 6th world. And the minigames, for the most part, suck.
Elebits is a possibility though. Very intuitive controls, but has some elements that might lead them to more advanced play (say, prepare them for Metroid and the like).
Other than that, Rayman is OK, though it has some challenging elements (the dance minigame will probably be difficult for non-gamers, as well as the marble maze and a few others).
