neither do enyone should give a f*ck if we control even a goddamn transexual shemale orc who also did a bleaching treatment because he/she wants to be a human.
Games are interactive entertainment, interactivity entails relatability. Different gender breaks away from that.
You could have already guessed it from 90% of games, the reason they have a male protagonist is that 90% of consumers of such entertainment are male.
This is really basic stuff people.
P.S.
Diablo 2 had gender locked classes and since Sorceress was the only mage of course people who wanted to play as mage were forced to do so. I myself didn't because it was, like I said, too immersion breaking.
There is nothing more basic than gender identity.
