I'll read the rest later (I'm on page two) but could TC answer me this:
I'm not advocating Status Quo, but why bother to write a game about a homosexual, when their sexuality has little or nothing to do with the game? Even in Robert Yang's article he admits that sexuality is a non-factor in his game. If a game was about, say, a woman trying to save her girlfriend from terrorists, do you think at the end of the day I'll care about their sexuality? Of course not, what I'd care about are their characterizations (and the plot/themes), and sexuality is so inconsequential that telling me that a character's preference for girls is as important as her personality and development will provoke me to slap you in the face with a well written book, and demand that you learn what it is to make a good character. You see, writing a novel about a character coping with their sexuality, be that character straight or gay, maker more sense than a novel that happens to have a gay protagonist. Honestly, I fail to see how you could incorporate the former into a game, so what does it matter to this medium?
I don't complain about the lack of Black characters (though I tend to play JRPGs, and thus deserve it) and any attempts to make one would make his/her skin central to his/her character (like the Tyler Parry movies *shudders*), or not matter much to the story enough to make it essential. So, if the character is Black, "Great!" If not, "Great game son!" Or, "I'll drag you're corpse to hell for making this shit!"
I'm also against heterosexual relationships in games, because there are so many more interesting things in a videogame other than, "Oh, they are totally in love! So cute!!!" like, you know, the plot. I'm not Asexual, but adding a relationship for its own sake has never appealed to me, and it takes a lot of skill to write a good romance, and even more to make it into a game.
To me, its all arbitrary. Sexuality and race add little, if anything, to the game. Sexuality is something that should stay where it belongs: books, movies, TV dramas, and Oprah, where the issue can be central to the story, or talk show. So while it would be great for you guys, to me it doesn't matter, because immersion doesn't rely on something so trivial. Ultimately, only one thing matters: was it fun?
