Star Wars: DroidWorks

Learn about physics and simple machines as you build your own Star Wars droids. Once you have selected various parts to put together in the droid, you pilot it through many different missions in a 3d environment. The beginning training missions teach you about the concepts. Once you get to the final mission, you'll be navigating your droid to find the Empire's Assassin Droid Factory so you can reprogram them to save the Alliance. (mobygames.com)
