BG1 NPC Project - basically 20 NPC mods in one, quality varies but you'll probably find one you like
NPC Strongholds - lets NPCs do stronghold quests you can't do
Unfinished Business - finishes and adds back in unfinished quests to BG2
Saerileth mod - so bad it's funny, Saerileth can die from a broken heart if you're evil to her.
Sandrah mod - another bad one, but this one spans the whole trilogy, sandrah can have sex with companions to cure them of their problems and gain their abilities.
