Although I understand the tendency to link this revelation to what we know of Ubisoft corporate culture, it actually just seems misguided and dumb to me.
The first things I thought of reading about this are movies like irreversible.. and not just irreversible, there are countless films with depictions of rape. I prefer to think such scenes are usually not there for salacious reasons (although there are doubtless some) but rather to alarm, shock and confront.. I've seen films that have such scenes and they are actually quite powerful and troubling, and that's the intent, there are reasons.. beyond thematic reasons, where the narrative and horror has meaning and is intended to stay with the viewer / consumer of the content, designed to provoke sadness or shame, anger, desire to see justice / revenge, or to provoke thought or a moment in public discourse - perhaps those depictions of sexual violence might have a place, that's up for debate, I know some victims would find even those depictions problematic... In any case: I can't imagine that place being any Ubisoft game, be it Splinter Cell, Farcry, Assassin's Creed! What the hell were they smoking? Did they forget games are supposed to be interactive leisure?
I can well imagine some gritty edgelord game director wanting to be 'brave' enough to do the game equivalent, but yknow - even MORE shocking - because you can feel it in the controller - wow. Stupid, but I guarantee you I bet they thought they were being artful rather than distasteful.. how it got as far as mocap?.. well that just tells you lots of loyal yes men (and maybe even women) were involved, that people were too afraid to object to it, or that people were ignored. Perhaps the people in charge just did not want to hear it was a bad idea. Having said that, we should probably count it as a small mercy it never actually made it to a production build!
I imagine whoever pitched that idea is watching this unfold now with some shame!
