But Star Trek Online is designed from the ground up to result as much fighting as possible. The galaxy's basically in a constant state of anarchy. If TPTB were to ressurrect the Prime universe, I'd prefer they used the novelverse's post-Nemesis backstory, which is far truer to the spirit of the shows and movies.
Not that I think they ever would - like Star Wars VII will most likely ignore their post-RotJ Expanded Universe. Trek's already done it once before - Enterprise rendered every pre-TOS story obsolete in one swoop.
