Some people don't understand the point of AC: Shadows being a success or a failure. It's not about saving Ubisoft: even if it's a massive hit, Ubisoft is fucked anyway.

We'll see, but if the game actually manages to be a commercial success despite everything, it will give the Guillemot family a considerable advantage in negotiations for a possible acquisition or financial partnership
