I think that there should be [i](if it's not in the first Destiny then maybe they can add it to the second part of the Destiny series)[/i] because of how it felt as if you were playing something new every time you got on Halo. It's one of the key things that kept Halo so unpredictable and fun because it wasn't non-stop campaign and multiplayer. If you don't think that they could make sense out of it since the game is a co-op MMO. Well, they could in the same way that competitive multiplayer will, you'll have to go to a specified in game location. The location can be justified with whatever suits the lore, traveler holographic training room, ancient lost civilization technology, whatever. If you think there should please add on to what I think. And if you think there shouldn't, give a decent explanation of why you think that forge mode shouldn't be in Destiny.
