If you waggle the Wii Remote, a character armed with a lightsaber will swing it with the same abandon you swing. If you jump or double jump first, you'll perform a slam or super slam attack. In addition, if you swing when a bolt is incoming, you'll be able to swat away blaster fire (rather than just having to hold your lightsaber still). Swinging the lightsaber with the Wii Remote is a bit faster than just pressing the trigger, and the effects you generate more powerful, but the real payoff is simply swinging your "lightsaber" in real life.
We spent a good chunk of time playing as a few Force-using characters in the Wii version of the game -- Yoda, Obi-Wan, Qui-Gon -- and were really pleased with the Wii control scheme. It's not the dueling game everyone is hoping for, but it fits the gameplay of Lego Star Wars and the Wii itself perfectly. It's fundamentally more fun to play Lego Star Wars swinging a lightsaber instead of clicking a trigger to make your character swing a lightsaber. LucasArts' task was to make the game a bit more ridiculously fun for adults but to keep it accessible for kids. It's a tall order, but one The Complete Saga looks ready to fill.
