This is why I love mods so much. The Valygar and Haer'Dalis romances are rescued, unfinished quests are finished, and characters can go from one game to appearing in the whole trilogy (my standard LI is Xan, in fact, thanks to Kulyok's excellent mod). I would've liked to see Beamdog do more in that direction, but to be honest, the modders already have most of it covered.
Of course when Beamdog went on to do Neverwinter Nights they decided the whole "adding content" thing was too much trouble, apparently.... though they have made some old modules available again.
