I know of a few games which tout 8 player via one player holding each wiimote or nunchuk.:
For one:

Bust a move also had this and Platchen will as well (they say 12 player, actually).
And for the record, I always thought 8 player SSBB with 4 on Wiimotes and 4 on GC controllers would be awesome.
"I mean, c'mon, Viva Pinata, a game with massive marketing, didn't sell worth a damn to the "sophisticated" 360 audience, despite near-universal praise--is that a sign that 360 owners are a bunch of casual ignoramuses that can't get their heads around a 'gardening' sim? Of course not. So let's please stop trying to micro-analyze one game out of hundreds and using it as the poster child for why good, non-1st party, games can't sell on Wii. (Everyone frequenting this site knows this is nonsense, and yet some of you just can't let it go because it's the only scab you have left to pick at after all your other "Wii will phail1!!1" straw men arguments have been put to the torch.)" - exindguy on Boom Blocks
