I don't disagree with this take...but I don't agree with it either? I dunno. Like, I feel like a ton of people played Alexios who were women, because they thought he was hot. And a ton of people played Alexios because you could romance men, and so that was gay representation. I don't think either of those reasons are wrong reasons for playing a male.
I played Kassandra because whenever I'm given the option to play a woman, I always do. (Exception being to Mass Effect: Andromeda, where I played a male to woo Cora...and wound up dating PB anyway...) But if Ubisoft's idea going forward is to allow everyone to play the game their way, I don't think that's a bad goal. So long as they stick to it, and hopefully this game has done so.
