I sometimes expect people to actually come along and demand romance for underage characters, since "immersion" has been brought up for almost anything else you can't do with them.
I mean, I hope it doesn't, but what I want and what is actually reality don't always coincide.
Anyway, one of the things that struck me in this article was the idea that only lesbians are interested in a lesbian romance, etc. When I went looking for some clips of the voice actors a while back, one of the things I noticed was that a lot of the gay romance videos were from women, and lesbian romance vids from men. This really shouldn't be surprising given slash fic, how heterosexual and male-dominated the lesbian porn category is, etc.
I mean, I'm not saying these people are a representative proportion, only that they break with the idea. Plus, men don't always play men, and women don't always play women.
Then again, literally the only reason I do the romances in a Bioware game is to get the achievement/trophy/shiny food pellet. Take 'em out and I wouldn't miss them.
