Romancing in RPGs is one of those things that i feel every game would lose zero value over simply not including. Hell romance in most forms of entertainment, including movies and TVs, tend to detract from what would otherwise be a perfectly fine story and it becomes a rather senseless inclusion or dramatic angle. Especially in games like D:OS2 where one selecting one rather vague dialogue choice can result in romance, a toggle option wouldn't be a bad thing. Sure the Fane romance was amusing at least, but man it was too easy to stumble into it. Ultimately I'd prefer if the genre alltogether just stopped with this weird fascination with romancing pretend and often questionable characters, but a toggle would be a sufficient substitute.
