Persistent World database tools like NWNx (and editing tools for custom character skills/items/terrain as new 5ed D&D books are released) built into BG3 would be an AWESOME addition for the multiplayer longevity of the game; once the singleplayer campaign is completed and players are starving for more content, the community can develop mini MMO servers for all shapes and sizes. Turn-based combat could function like Divinity 2 where you remain outside in real-time until you attack a combatant or get noticed by them.
