Depends; are we talking the Special Edition, or the original cut? Because if it's the former, play some TF2. If it's the latter, what are you waiting for? You've got Star Wars to watch!
Edit: Oh, also, I came into this thread expecting the question to be whether you should play a Star Wars game (Battlefront II was what came to mind) or play TF2, which would have been a much more difficult choice.
