The guys at Leakerz.net managed to film their gameplay experience of SWTOR at Gamescom. There's more than an hour footage of the game.

First, the Trooper and Smuggler gameplay videos (http://leakerz.net/wp/2010/08/20/star-wars-the-old-republic-gameplay/). Then some Imperial Agent footage. (http://leakerz.net/wp/2010/08/19/swtor-imperial-agent-gameplay/) And last but not least, Bounty Hunter and Sith Warrior gameplay (http://leakerz.net/wp/2010/08/19/star-wars-the-old-republic-gameplay-videos/).

I was kind of hoping for something different from the user interface, but it looks like your standard MMO interface which I suppose isn't a bad thing unless you don't like MMOs or don't play them in which case it will take some getting used to.

The trooper gameplay looks kind of pedestrian imo...and by that I mean pretty much point and shoot but I guess to expect more probably isn't realistic.

I like the Imperial Agent more and more though the player in the video seemed to be intent on playing an in your face run and gun style of play which isn't how the class comes across when it's described.
