Just finished this one, fun and violent! If you finish, let the credits roll for a while and you'll be able to play as the leader of the Riffs beating on the Rogues for a short while.
After that the "Armies of the Night" video game becomes unlocked in the Warriors hang-out. That was fun, a cheesy side-scrolling game with 80's style video game music to it.
Now on to Battlefront II.
