um, read on, i explained it dude... "Size might mean nothing to the force itself, and the ability to destroy a planet may be insignificant next to the power of the force BUT, the person who USES the Force is another story altogether, it took quite a bit out of Yoda to pick up Luke's X-wing, and shortened his lifespan a few years, and he struggled hard to concentrate on getting a hold of that large power conduit or whatever it was that was about to fall on Anakin and Obi-Wan on Geonosis."

yeah it's mainly them just going nuts with the Physics engine for the game and using "the force" much like how Half Life 2 uses the Gravity gun, little more than a gimmick to show off the game engine.

what i would like to see is a new TIE Fighter game or something with that kind of engine, so you can blow holes in ships and see the crew float out from the breach.
