BioWare has been teasing us with info for Star Wars: The Old Republic for some time. The upcoming MMO lets you choose from a variety of classes based on classic Star Wars characters, including Troopers, Imperial Agents, Bounty Hunters, and Jedi Knights, and fight for control of the galaxy, whether you pledge your allegiance to the light or dark side. We've had questions of whether BioWare can pull off such an ambitious game, doing justice to both gamers and Star Wars fans. This new trailer, made entirely of in-game footage, has reassured us for the time being.

The video shows off a variety of familiar planets, as well as glimpses of melee, ranged, and space combat.
