in a interview with Todd he said something like the quest's will never be the same... does that mean that if you do 1 quest and later on do it again on a diff chara. does the quest evolve to your chara or something? Or did i just hear him wrong?
remember radiant give you quests over your 2 highest skills.
So if you come with a thief like character you will have a diferent quest than a warrior class character.. there may be other variables too.
