Edit: To be fair there is something you could do to this that might make be buy it sooner and closer to $50. I've heard that the dLC packs are these little separate mini games that use a lot of interesting stuff but you can't use that stuff in the main game.
Change that so everything is inside the same "game" and I might just buy this for my pc. (I believe it is this way because memory limitations of consoles meant anything they added in these dlc packs had to had something removed from the main games memory for it to work.)
