Yeah, it's plausible that it could. But most likely only if you had friends over or often. If that's the case, it's likely it could. But I'd highly recommend getting something else, preferably Zelda, to go with it.
Hell, I've avoided playing Zelda just so I can wait until my component cables come in. TOMORROW. FINALLY. OMFG.
But pretty much, we've been having Wii Parties that last up to 10 hours. It's been great fun and uh, about 8 of those hours are Wii Sports, 1 being food, and maybe 1 of misc other games. More likely? 9 hours of Wii Sports out of those 10.
