Get alot of mods. There are plenty lists out on google, but the banter packs and fixes are a must and then, companions and quests as you like.
BG1/2 is great, but the mods make them genius
The restored content mods maybe not at first, but certainly the fixes/tweaks mods.
One of the reasons I can come back to BG:2 is because there was only so much content you could really get in one go, this also makes the modding community's contributions fit in easily, though the writing is sometimes a little amateurish.
