Hey, I think you better install it. I say its worth your time. I play a zabrak (darth maul) sith juggernaut, complete with a black cape and respirator. One time in a flashpoint, it was decision time, and one of my group members said that they were trying to be a good bounty hunter, to which I replied: "f u I'm evil".
In another flashpoint another player said that she never watched any of the star wars movies except the ewok movie and then I said: "burn the witch". but then a few minutes later she said had a husband that was overseas so they both play online games together. And she was introduced to the old republic after playing Cod for a while. It was an interesting story.
