Very late to this conversation (I just joined the forums) but wanted to put in my 2 cents on the issue --
First, I like the idea of making sure all relationships, be they romantic, platonic, brotherly, hateful, or in between, are well developed. And I would rather a handful of extremely well developed companions who can develop unique relationships with the PC than a large number of companions who are shallowly written.
Second, in RPGs, I am all for romance, and I am all for sex (non graphic), but I do not want to be given the impression that romance=sex. Sure, there are romantic relationships that are also sexual relationships, but there can be also romantic relationships that are not sexual (or not for a long time) and there can most definitely be sexual relationships that are not in the least romantic. More to the point in game design, it really really irritates the hell out of me in video games where the moment you bed another character is determined to be the moment you successfully "romanced" them. I hate when "romance" is used as a euphemism for "screw." Using an Obsidian game as an example, Alpha Protocol does this rampantly. Banging a girl you hardly know after a long day of shooting people just because you let her bandage your wounds, or having an "exclusive interview" with a journalist who has been largely and entirely been cool and aloof to you the whole game, or letting a mercenary ravage you on a table is not romance--it's just plain getting laid (I want to use a different term in fact but I'm fairly sure it would get filtered out). So don't tell me, game, that I successfully "romanced" these characters when all I did was bang them at a moment of convenient opportunity (I don't even think you ever get to tell any of the bangable women that you love them, and I'm pretty sure with maybe one or two exceptions, Mike doesn't). I don't mind that these events can happen--I in fact quite enjoyed them --but just call it for what it is.
In fact I think to this day, the most satisfying romance I ever felt I played through--in any video game ever, not just any Obsidian game--was Annah in Planescape Torment, which culminates in no more than a quickly cut off kiss and of course more or less ends tragically. But through the dialogue, I felt the tension there, and I could see clearly how she felt and how she struggled with her feelings, and thus it felt to me like a real story of love. The moment where she says, "He matters to me more than life," actually made me cry. It's not often that I actually feel in a game like a character truly loves my PC, and Torment is one of the very few that accomplished that.
Now, just in case I haven't made it clear, I have no problem if there's "bedroom scenes" in a game, but I just want to be clear of the distinctions between lust and love (and the spectrum between), and that one does not always immediately come along with the other. Hell, I'd think it was awesome if there was a companion who beds the main character on a lark but then makes it absolutely clear that they have no particular feelings at all toward the PC (and perhaps by contrast, an NPC deeply in love with the PC but who is very slow to admitting that, let alone to seeking out physical intimacy).
