I might be all the mods being added to BG3 adding more replayiblity, like a Magus class, Death Knight class, Crimson Oathsworn class, Blood Hunter Class, Red Mage Class, mods that add subclasses and subraces, mods like Races of Multiverse that add 56 more races, a mod that adds in Satyrs, a mod called Avengers of Balduran that radically changes how the game plays like adding permanent injuries, etc....
