We have two tags for the Star Wars: The Old Republic MMO:
Since sw-the-old-republic has six questions and two followers, and swtor only has three questions (one of which is also tagged sw-the-old-republic) and zero followers, I suggest making swtor a synonym.
You can vote for the synonym here.
On a related note (since there are currently only two users with enough answer score to vote on this), should we expand the scope of sw-the-old-republic to include the entire Knights of the Old Republic sub-franchise?
