Divinity: Original Sin 2 has a GM mode and you should try it out.

If you haven't heard of it -- just google/youtube it. Basically, Divinity: Original Sin 2 is an isometric RPG much like NWN.

I got to Act 2 in the campaign before getting exhausted with it (way too many battles around every corner for my tastes) -- but the game also features a very flexible GM mode much like NWN1's, if not better, as far as the tabletop feel goes.

It's currently capped at 4 players (not including the DM), but I have no doubt that might change with mods in the future. Even at 4 players, it's pretty freakin' great. Recommend y'all to try it out and start rolling 20s again.
