As Fruit Brute mentioned earlier, The Escapist's Robert Yang just wrote an article, Not That There's Anything Wrong With That, explicating the response to his nominally gay Half-Life 2 mod, "Handle with Care."
The premise of the mod is relatively simple, you start across from your marriage counselor, berating you for not letting your partner speak; which plays on the knowledge that the person you inhabit, much like in Half-Life 2 never actually speaks. Continuing to point out the problems with the gameplay in his mod (you move stacks of boxes around in a warehouse), Yang points out how the references to this being a homosexual marriage in the game are relatively simple and inobtrusive: your partner is a he, you are a he, and the word partner is used, but the references are minimal.
This then created a furor enough to have people post angry responses on his website, and that's where this article really focuses; because when people demanded he change the game to include less 'gay,' his response is, "Why on Earth would I do that?"
As he quickly states:
In a way, "Handle With Care" isn't really about gay marriage at all. With only one casual mention of a word, the significance of which was likely lost on many players, it's hardly anything to talk about. What about the mind-bogglingly frustrating gameplay, the inconsistent implementation of physics or the esoteric in-game "visions" that resemble mediocre video projects cobbled together by art school dropouts? I expected criticism of my work, but to me there were far more pressing issues than the player character's sexual orientation.
How you respond to the rest of the article depends on how you feel about the use of the words 'gay' or 'faggot' used in colloquial speech. Your mileage may vary; the word faggot does anger me; I am, admittedly, generally an angry person.
What really struck me is his reasoning for creating his mod as he did:
So yes, in a way, my mod isn't about gay rights at all - but that's also perhaps why it's almost entirely about gay rights. It's about how a gay person's life has all the humor, pain, happiness and anxiety of a straight person's life, how the two are otherwise indistinguishable - and yet gay marriage is still recognized as mere partnership, a transaction devoid of emotion.
