Well the main problem with the obsession IMO is that none of the Bioware writers so far managed to put in a really believable homosexual character.
I think Bioware process goes like:
Let's make 9 characters 3 bi 3 gay 3 straight, then give them personalities so you can tell what orientation they have.
Instead of let's flesh out 9 characters then, if we got time, worry about who likes it which way.
Yes, I agree - which is why I specifically mentioned quality writing as being a low priority. Well, that, or they simply suck at it.
Now, I admit to not paying too much attention to the sexuality of other people - and this goes for both real life and computer games. I also have a similar reaction as a gamer as a I do as a real person, which is negative if the nature of someone's sexuality is forced upon me as something I have to care about.
The thing is that I find it very, very mundane and completely incidental. The only time I care is when it's relevant to my own person, which is obviously if I'm into a girl. That's when her sexuality becomes relevant to me.
My experience with Bioware characters is that they're almost ALL in-your-face when it comes to their particular profile, and we're not just talking sexual preferences. If a person is an assassin, then it's shoved in your face that this person loves to kill - and we have to immediately get exposition about whatever justification these simpletons find for themselves.
There's very, very little in the way of subtlety and the grey area spectrum is hardly being used. When the grey areas ARE being navigated, it's without subtlety and there's this writing campaign within the game to make it apparent that it's oh-so grey, which means it's not grey at all. Grey isn't middle-ground bent in neon, it's simply reality - and the best way to present reality is to let the gamer make his own call without nauseating embellishment.
This is boring to me, and it's a huge turn-off. When the thing shoved into my face becomes something as trivial as the sexual preference of any given NPC, it's worse.
In the end, I simply don't care for Bioware's approach to writing at all - and their pathetic and banal way to push "sexual equality" is downright nauseating.
It's like they've never spent a day in their lives dealing with real people with real personalities, that happen to go FAR beyond their sexuality. Unless, of course, you happen to be a gay person who's made that sexual preference the key to your identity.
In which case I'd feel sorry for you for not having something more interesting at the core of your being.
