Borderlands (which made Game of the Year on it first) is about to release number 2. It has started its advertising campaign. Many people like myself would definitely say RAge is better and more grown up.
Borderlands & Rage are obvious combatants as both games are similar in many ways.
Would it not make sense for a Rage dlc to come out and sell of the back of Borderlands 2's success?
Look at how many rpg games are now selling off the back of Skyrim.
