I don't like how my character responds to a lot of the prompts in the game. Instead I just imagine something else was said that better fits the character I believe my character is... I cant imagine them being as sassy or sarcastic in every response as I want to be so I don't blame the development for not including it.
Person above makes a decent point... the game is 3rd person not first... sort of. More of watching or reading someone else's story, by that line of thought you should not force your gender identity on her/him.
Under that same reasoning though... you could say they excluded characters that would have been assigned male and identifies as she/her... They are missing out on gender diversity, but... they do have some NPC's that are diverse.
Who's to say the your character who is male/female isn't post/mid transition?
I am a lalafell.
I also identify as gender apathetic. If people are polite I do not care what they call me, and I know that may sound like a cop-out.... But its not. I play both male and female characters and both ways people address me as he/she are fine. I also work tech support. I take calls all day or make calls, when people complete surveys or pass the phone to some one else about 70% of the time they will identify me as She/Her the reset of the time as he/him. The only time I have any problem is when they clearly say it in a demeaning way.
