In this thread I'd like to briefly introduce a wide range of quest mods, for the benefit of other players who are looking for more content to explore in Baldur's Gate: II: Enhanced Edition.
All of these can be installed on the current version of BG2:EE; most also on EET and on the original BG2:ToB.
The list is not exhaustive, but I may update it to add more entires in the future. I'm also interpreting "quest mod" pretty liberally. And although I'm ordering the mods by their original release date, please note that old does not have to mean outdated or unmaintained!
