For those of you getting excited about this MMO, you can easily get a quick fix by playing the old Bioware KOTOR games. The lore, story, and basic mechanics of play (story driven, planet locations, voice acting, basic combat) in these games is what the MMO is based on.

I bought Sith Lords for $16 from Amazon and already had the original KOTOR. They are fun to spend some time with in anticipation of the MMO.

You do have to do a bit of work to get these games to work on newer operating systems, but it isn't too bad. Just follow the instructions in this forum link:

Lastly, there is a nice YouTube channel on SWTOR called SWTOR FTW. Has very detailed videos for each class that may help you decide what you want to play. Look it up or follow this link:

Have fun!
