I would like to see an exclusively-gay love interest. It wouldn't have to be Vega, but at least one homosexual love interest amongst all the heterosexual ones would be really, really nice. If nothing else, it would be
awesome to have a kick-ass gay hero in fighting Reapers in space with me. (What can I say? I think the world needs more gay heroes and role models.)
I remember that David Gaider discussed the "homosexual love interests versus bisexual love interests" issue before DA2 was released. In short, he that Bioware prefers to make bisexual love-interests because it "covers all their bases" and makes the most content available to the most people, and I get that, I really do. But I also remember that
after DA2 was released, David Gaider admitted how surprised he was by the number of people exploring the same-sex relationships. It's not just gay gamers who explore the gay content (see Yahtzee's
article to see this discussed in length) just as it's not just straight gamers who explore the the straight content.
So, maybe Bioware is starting to figure out that it would be worth their time and money to invest in an exclusively-gay love interest, and I firmly believe that Bioware
will make one... some day. Maybe not in ME3... even though I've got my fingers crossed for it.
