In-Game from MSNBC have posted a brief video with their impressions from (presumably) playing the press beta of Star Wars The Old Republic. In the video the narrator describes how much fun it was to play a "bad" Jedi, taking all the evil or morally questionable choices while still being on the "good" side.
Their impressions, along with every one else, seem to be good. It would be nice to see some actual in-game footage rather than clips of the various videos Bioware put out, but hopefully Bioware will drop that NDA soon. I am getting somewhat good at spotting each clip when I see it!
