Heck even in Bioware, we rarely see female variants of Turians, Salarians, Elcor, Hanar, Batarians, Volus etc due to to the amount of resources and time it takes to include these female variants. (There are no lore reasons not to).
That said Bioware does include both gender variants of humans and quarians. There was Omega DLC which has a female Turian (which I won't spoil for you). A female Turian was playable later on in multiplayer. The multiplayer allows gamers to play as both genders for Quarians, Humans and Turians.
True but female Shepard's animations are just a recycled version of male Shepard's animations which people complained about. Ubisoft want to give new animations to their female characters so I can respect them on that. Bioware is known for recycling animations and they do it because it requires less work.
Animations: I don't pay much attention. I am told however that men and women move differently. Yes there are noticeable differences between poses, women tend to cross their legs (especially if they're wearing a skirt) etc. However there are plenty of subtle differences. Some gamers found it off putting that female Shepard had identical animations to male Shepard despite her different frame. In Dragon Age 2, some gamers remarked that the "butt wiggle was offensive".
The problem with a female Hawke is that her running animations were poorly done.
On the topic of this "controversy" now:
I don't know why it's so difficult for some people to understand that resources and time is required to create a female character who isn't just a male character with boobs and a wig on. Ubisoft just didn't deem it a necessary feature and focused that development time on gameplay mechanics this time around. People should be calling them out for not being innovative with the series rather than them not including female assassins (something they have previously done so the argument that they're sexist is ridiculous).
This is why gaming and game journalist is going down the drain. There are bigger problems. No one complains when there's a majority male-star cast in a movie with females only being a supporting minor cast just like no one complains where there's a movie with a female protagonist at the focus. If it's a game though then there's a huge outcry.
Double standards if you ask me because last year in Tomb Raider, we were playing as Lara Croft slaughtering men (and only men) on some remote island. Where were the women? Now imagine a role reversal with Lara Croft being replaced with Nathan Drake fighting against a tribe of amazon women and they're the only enemies in the game. We'd get Eurogamer, Kotuku and Pologon screaming sexism stating that the game is some misgonist's dark fantasy because Nathan is going around slaughtering women.
Guys, they're games. Some games will have gender-selection and some games won't. Deal with it.
Want more games with female protagonists? Then get more female developers into the gaming industry. That's the real problem if you ask me. The industry is male dominated so why act surprised when most games are developed with a male and straight audience in mind?
