I don't really feel able to vote until after I've tried all six romances, and seen at least some of the romance conflicts. So far I've played and enjoyed Xan, Shar-Teel (and that was a surprise) and Branwen, and I'm part way through a game where I'll have both Xan and Coran in the party. I suppose I could get an impression of what the romance is like from reading the Dialogues, but that wouldn't be as much fun.
Of course, if there's a cutoff date for the poll then I'll just have to play a bit faster. Anyone got any good symptoms for time off work due to illness.
