This is a very good trailer. Don’t you think that the main baddie looks like Darth Vader, sans the metalic casing? Very exciting sword fights and all. But, I am quite sceptical over the game play. Not until I see the in-game trailer

This trailer was released in E3 2009.

The game is going to be an MMO (Massively Multiplayer Online) and features something interesting (for the moment):

… every non-playable character in BioWare’s upcoming PC MMO Star Wars: The Old Republic talks. Every single digital denizen BioWare has created to populate the game’s universe will have something to say. Useful dialogue or not, this is an impressive feat — an industry first, as we were told during Electronic Arts’ E3 press conference this afternoon.
