I agree about the Jaheria romance, her lack of trust really got to my PC when I romanced her through the whole saga, though IMO Jaheria is pretty solid. For a male's romance, I'll put my 2 cents in for Viccy, regardless of alignment and whether you have a happy-patch. Though she can get on your case (be ready to put up with some flak), she has steely nerves (and doesn't whine, IMO whining in dungeons is not only annoying it seems to be a pretty bad sign for adventurers, who make much of their fame underground), is quite a fine mama, makes a great tank with some strength items (a super-low AC will help her spells from being disrupted as well (in addition to the mirror spell), has a rocking MR (with the Cloak of Balduran from BGI it is easy to make her immune to magic, same for Solafein (which is one of the fine mod romances for open-minded male PCs (nothing personal guys
) and females), and if you are a mage and have an NPC immune to magic, send them into the fray while your PC unloads magic, quite fun), and ends up with so many spells (even single-class clerics get quite powerful if used well). If your rep gets too high there are easy ways to adjust it, like a little careless theft, which is always fun in BG
or (little Spoiler, highlight):
by having your PC shapeshift for a little while after the underdark
And if you take her to ToB (another vague spoiler, highlight):
if you have good-intended talk with her, she has a nice surprise for you after some point...
Just my opinion, a case could be made for any of the romancees. Overall try them out and see who works for your style.
Tired of working here wanted a holiday was thinking of retiring probably going to die. Time to move on under down... down down.
