Ah the Wiimote. An elegant weapon, not as clumsy or as random like a blaster. Paired with the Nunchuk, it's pretty awesome too, according to this video from G4, which got an exclusive hands-on with Star Wars: The Force Unleashed for the Wii's duel mode. (Man that was a mouthful).
G4's reporter went as Luke Skywalker, duking it out in a TIE Fighter bay with Asajj Ventress There's saber-slashing and Force-choking galore, all arising from a pretty shrewd use of combinations and reverse moves in both controllers. It's not all lightning bolts and throws, either. Check out that old-school kick to the grill Luke delivers at the end.
The video says you'll get 9 different arenas and 27 characters to choose from, classics to the expanded universe. I know that LucasArts is promising exclusive gameplay for all consoles. But I had the two Jedi Knight games on Xbox, where lightsaber combat was a lot of button mashing and getting lucky. Honestly, if the purpose of this is to at last swing a lightsaber in 1:1 combat, then this is your baseline version.
It's probably going to make me buy a Wii. The question, will it make others do the same?
