I wonder if Arkane continue seeing benefits by this game, because it's property of Ubisoft.
You mean if they get any share from Steams' sales for example? I don't know how Ubisoft and Arkane Studios would split it, but aside from profitting from the sales, Arkane Studios have at least the experience from designing the game. I see no reason why they can't tap all that good stuff from DMMM into another game- this time owned by maybe ZeniMax?
oh right. ubisoft is a pretty awesome game company though. I'm sure they could take up that hat too should it come to it.
