One of the most ambitious pieces of Star Wars "merchandise" must be LucasArts' massively multiplayer game, Star Wars Galaxies. It opens your PC up to a world where you can live in the movie's universe, and wander among hundreds of other fans and role-players. Shortly before Episode III: Revenge of the Sith hits theaters, Galaxies has its own third episode to unveil -- an update that'll once again bring changes to the gameplay, give players more to do, and add new storylines to become immersed in.
