If he doesn't like Mario then I don't know what to tell ya. I don't like Mario either and I think the Wii is good for a few other titles, but I don't know if there enough to warrant a purchase from your friend.
No More Heroes 1 + 2 is pretty cool and very interesting.
Silent Hill: Shattered Memories is very good.
Monster Hunter just came out.
The Metroid Trilogy is a very worthy pick up.
You've got a new Zelda coming out this year and Twilight Princess has been ported to the Wii with motion control's added.
Despite what everyone else say's, the on rail shooter's on the system are pretty fun.
I haven't played it yet, but Red Steel 2 is meant to be very good (I played the first and it was horrible, they fixed everything in the second).
Super Smash Bros. Brawl is fantastic.
That's all I can think of what I like about the Wii, so I hope that help's.
Bet with Conegamer and AussieGecko that the PS3 will have more exclusives in 2011 than the Wii or 360... or something.
