"One of the most hotly anticipated PC games on GameSpot at the moment is Lucasarts and BioWare's upcoming massively multiplayer online role-playing game, Star Wars: The Old Republic. Mixing George Lucas' epic sci-fi universe with BioWare's successful role-playing experience seems like a pretty safe bet after the success of the Star Wars: Knights of the Old Republic series. That game mixed successful MMO pillars, such as combat, progression, and exploration with something BioWare excels at: compelling, narrative-rich storylines. Announced late last year, details about the game have slowly emerged since then, and so far, we've seen a number of Empire and Republic classes, including the bounty hunter, smuggler, trooper and Sith. We finally got a brief play of SWTOR as a Sith warrior at GamesCom 2009 in Cologne, Germany."
As is the case with any and all pre-release previews/demos, proceed ahead "at your own risk" for the sake of spoilers.
UPDATE:IGN provides us with a fantastic look at the first walkthrough footage of Star Wars: The Old Republic in the form of a 4 part video. All 4 parts are embedded below for your convenience, though note that the video is age restricted. Getting more excited for TOR?
