If I want to play most games in genres other then RPG yeah I have to play a guy and find some reason to want to be there if not for the hero or his cause then the world but I do prefer to play as a woman especially if she has the same respect as the male hero part of why I love playing fshep.
I can't say on the whole is it a big deal studies say no not really men will switch genders when given the option more so then women. My nephew's friends question his choosing to pick heroines in games and when I questioned his friend as to why I got the," I don't know it just is," and the ever popular, " girls can't be adventurers." really he said that so its still out there and when we tell him I game and have my own console he goes, " Can I play yours?" and I go , " Nope, cuz its mine." However the game publishers and some developers tend to agree with my nephew's friend no one wants to be a woman so the very idea of having one in most games is never thought of, too much effort to implement, it was an option till they had to cut corners to bring the game to market, or she must be changed into a he so we can sell copies.
