Well, I'd beg to differ that there is no debate here except for the fact that the OP stated that they're not a hardcore gamer. Since the system will likely only be used for a couple games here and there, the Wii is probably best - still I'll give my 2 cents.
While the wii is great for involving people - girls mostly - that you want to get involved (especially when drinking), some of the most fun I've had with the other gamers is online xbox live while drunk.
In my opinion it all depends on who you're drinking with... if you're a gamer, then fragging people in Gears, Halo 3 (beta was fun), Perfect Dark Zero even has been pretty awesome for me.
But there's no denying it, its still fun to play wiisports with a few chicks who otherwise wouldn't touch a controller. The downside is, you still have to treat them like you would on a normal system, since just because they'll pick up the controller doesn't mean theyre competitive...
