Jonathan Cooper, a former Assassin's Creed designer says that Ubisoft's claims about the complexity of adding playable female character options in Assassin's Creed: Unity is bullshit. Cooper, who now works at Naughty Dog, says that such a task would be simple to implement. In fact, he says it would be one or two days' worth of work.
"In my educated opinion, I would estimate this to be a day or two's work. Not a replacement of 8000 animations," Cooper said on Twitter.
"Man, if I had a dollar for every time someone at Ubisoft tried to bullsh** me on animation tech," he added.
Cooper went on to say that the female main character of the PlayStation Vita game Assassin's Creed III: Liberation, Aveline de Grandpre, "shares more of Connor Kenway's animations than Edward Kenway does." Connor Kenway was the protagonist in Assassin's Creed III, while Edward Kenway played the lead role in Assassin's Creed IV: Black Flag.
Cooper added that when he worked at Ubisoft the company created a prototype for an unspecified Assassin's Creed game where if you entered your name as "Aleissia," you could play as a female character.
