Right, I have classical music playing behind me so that I'm not going to be annoyed. Yeah, it's Mozart's Requiem but that's my choice.
As is the sexuality of your hero/heroine.
Of all the thousands of characters available to the player, I would count less than a hundred whose sexualities are inferred, and less than ten who are stated.
Especially given the idea that sexualities in games are far more diverse than simple hetero/homosexual. They can cover aliens, robots and other races. Problem with that is that a male human loving a male alien would actually be Heterosexual, as Hetero- comes from the Greek word heteros, meaning "different" or "other". Perhaps Xenosexual. Who knows?
3 years ago, this was covered in the gay papers with the GayHealer [http://www.pinknews.co.uk/2006/09/28/web-bans-gay-characters/] fiasco (Pay special note to the comments, some are from LGB players) and it's cringing backdown [http://www.pinknews.co.uk/2006/09/29/web-game-sparks-gay-debate/].
Now, given that a year ago we had an article on how there's no "black" heroes, followed by a list of all the known ones, who was the main villains then?
The white-male-heterosexual.
Now, I fall into that category, and, as far as I am aware, have NEVER acted against a gay person and have not received special treatment above what I achieved under my own merit. While I can already feel the hatemongering shower down on me telling me that "YOU ARE PART OF IT SO YOU ARE GUILTY!", please tell me what I'm supposed to give up just because of my low-melanin, XY gene, girl-liking heritage.
Perhaps what you're looking for is the rich, powerful, ignorant, white male heterosexuals? or even the people pretending to be white-male-heterosexuals? Because if you believe that a non-white, non-male, non-heterosexual is incapable of exactly the same amount of prejudice, then I suggest you look a lot closer at the world.
If you're in a single player game, make the character whatever sexuality they want to be. It's not as if people have misrepresented their sexuality to get what they need before, and that's all your character is doing.
Or you can pop down to the slash sites where I can assure you that Gordon Freeman, Master Chief and the others will be deep in rampant action.
