An openly homosexual main character, in a game where you can't choose what the main character is into. Bonus points if the character is also in a relationship.
This! This!
Yas!
You know what else would be cool too? An older main protagonist. I want a badass grandpa or grandpa as the main character.
More diversity in general would be good.
It seems that most characters in video games are young, white and heterosexual.
Some variation would make things more interesting.
