Joystiq (among others) reported on a video of the physics of Star Wars: Force Unleashed. Here’s a video demonstrating the three physics engines:

My first thoughts were of the ‘Wow’ variety. On a technical level, this is simply amazing. Especially the way objects are deformed appropriately. As the comments on the Joystiq article state, some of the effects are just not realistic. Mainly, my problem is with the supposedly AI driven stormtrooper reactions. It just seems like they’ve gone out of their way to make the player notice the stormtroopers reaction. A good AI will be something you don’t notice directly unless you’re watching closely. Just as physics had to grow to the point where we now have deformable objects, I think this AI approach will have to grow. But the idea is promising.
