Veezy's update makes perfect sense, but my assumption, based on experience, is that those gay romances will be poorly written.
If there is an outrage, presumably it should be directed at how Bioware consistently makes gay relationships look really stupid (the only not-stupid relationship I can think of was that one dude in Mass Effect 3, but that wasn't playable).
From my experience with their romance system you generally have to be continually nice to NPCs and their last games I played there was a very obvious point where you could pursue a romance option. Their earlier works were more prone to "accidental romances" but definitely by Dragon Age if you were getting in someone's cot you either had to be extraordinarily dense or actively pursuing it.
(Though there were some pretty hilarious threads on the BioWare forums of "angry" players who were "tricked" into sex by Zevran.)
I took a knife that fixes mirrors (WHAT?) from elfgirl in Dragon Age 2, maxing out her angry meter... so somehow we had sex, rather than her leaving my party (WHICH WAS MY GOAL).
I almost had sex with Insaneguy when Bioware decided to give me two <3 options and one homophobic option. The game seemed to really, really want me to have sex with Anders, because it was either "yes, let's bang," or "oh god, ew, gay people, amirite!?" I think it was trying to say "no reasonable person would say no," but judging by the hearts sitting next to the other options, it was going to end in sex.
Despite hating the elfgirl's guts, I somehow felt responsible for her, and oddly, desirous to gigglesquee glomp her. So I picked the homophobic option, not because I wanted to, but because it was the only option that prevented me from cheating on the elf whose head I was determined to nom on. Or something. I don't really know. Bioware's writing has magical powers.
I figured that since I was already a mass murderer in video games, selecting a homophobic choice didn't really reflect all much on me, especially since I was personally angry at Bioware for somehow putting me in the situation. It did feel weird, since I was playing as a Paragon, but then I remembered that the game's writing was batshit insane. I think some Bioware writer must really be into Yaoi or something, and was so desperate to make this occur in everyone's game, that he/she/it made that situation occur because they figured everyone would be too nice--too invested in the story and their character--to pick the homophobic option.
Well, fuck you, Bioware. When I get mad at games, I pick the stupidest possible dialog bits. I'm not invested enough to care about what I'm saying is socially acceptable or not. I pick the dumbest options possible because it makes me feel like I'm spiting idiotic writers. I
also picked the "I want to be a dragon" dialog.
I guess what I'm saying is that accidental sex in Bioware games is definitely possible, either because they're bad writers or horrible ones. I'm still not sure.
