Absolutely. I've found that romance tends to help add to an rp and its story, but it all depends on the particular players, characters, and how that romance comes about. If it's an unplanned, natural extension of characters' interactions within the rp's story, it can help work as nice character development and drama for the characters and generally be an interesting experience. 

However at the same time, there's a lot of ways in which it can go wrong, which can immediately turn me off it. One of those is if it's something that's forced between two players (who 'ship' their characters) and not something that's been built as a natural development of the characters' prior interactions. It just reads as forced, unnatural, ignorant of other players within the group and their characters and also just appear as... kind of boring. It depends on the type of romance, I suppose, but as a whole a pairing that's forced through into an rp tends to just be kind of awkward. I'm also not really a fan of some instances where players either rush through a romance development to the point where again, it's unrealistic and unnatural, or if players push that romance to the forefront of the rp to the detriment of other characters and the main plot itself, and instead force the focus of the rp onto it. That's always pretty shit. 

But overall it comes back to and depends on how well written it is. I think romance can help add a lot to an rp as a subplot, so long as it's done naturally and with care, but that could go for a lot of other things too.

EDIT: Also I appreciate the effort to bring more life into the RP Discussion forum. I haven't seen any topics here that's caught my interest to reply to for a while now, so kudos for that.
