I forget where the interview was, but the Borderlands crew was not happy about Destiny 'borrowing' some concepts. Rage tried to, and failed miserably. Borderlands had a set of humor and stuck with it. Destiny tries to be all serious, but then you have some of the weapon names: they don't fit. Both have you repeating everything all over, however, Borderlands has a lot more side quests. Granted, many are fetch or go kill X, but at least it seems like there was much more to do. I have a feeling the prison is simply the arena from boderlands. I guess we'll see next week.
