This came out of a discussion in the Confessions of a Bhaalspawn, where we bothered @SapphireIce101
to list her five favorite romance mods. And romance mods = NPC mods, generally. Not all NPC mods are romance, and not all romance mods are NPC mods, but I figure the two of them are connected enough that we could talk about both in the same mods.
So here it is, simple enough- what are your favorite romance mods, and what are your favorite NPC mods? Don't just tell us the names (unless you really don't want to type more); tell us why you liked them, or even the parts you disliked about them. Talk about BG and BG2; that's why we're in general modding and not a subforum.
I'll post my experience with BG1 romances here after I eat dinner. But in the meantime... um... everyone post! Tiax demands it!
As a note, my interest is somewhat selfish in this. I'm planning a playthrough of BG1 with a male character to test a few things out, and he'll probably romance Branwen. But BG2? I could go with Branwen again, but I've romanced her many times. If anyone has played any good mods for a male in BG2, I'd be interested in hearing about them.
