This is a bit of a thread necro, but I don't see any newer discussions about NWN:EE that are similar.
Having recently gotten back full throttle into the Neverwinter Nights community, thanks to the Enhanced Edition, I have to say that for multiplayer NWN:EE really has given things a new lease on life. And there should be (fingers crossed) some more development to come.
I've run a weekly NWN campaign since 2004 (including a couple periods on hiatus), having started it out at the old Neverwinter Connections, and in January converted it over to using NWN:EE. The graphics for modern monitors and the new/revived MP features from Beamdog really do make a difference to the current experience, plus it's significantly faster and more stable, including in the toolset, than my copy of NWN Diamond is on the same computer.
One major difference nowadays is that multiplayer revolves even more around a fragmented persistent world (PW) community than it used to, I think in part due to the demise of the old Neverwinter Connections site (neverwinterconnections.com) in 2012. Now that the new Neverwinter Connections has been re-launched at https://neverwinterconnections.org I'm hopeful that both PW and more classic D&D style campaigns and DM'd modules can be promoted and supported across the multiplayer community.
