I always make an ass of myself in these sorts of discussions.
What I should have said is that, as a white, heterosexual, male, it's easy for Ian to say that people shouldn't look for representations of their own race, gender, ethnicity, sexual orientation, and whatever. It's easy for him to say that they should just have fun... because he is fairly well represented in video games.
...It's not that a white person couldn't enjoy a game starring a black person, or vice versa. It's just that when you are never represented, I imagine you would tend to want to be. If you're gay, that's a pretty signifigant part of your life. And then to go and play games where you do nothing but save your in-game girlfriend, where all the npcs are straight, etc...you'd have to want some sort of at least respectful acknoledgement of homosexuality, in videogames, once in a while.
