Dark Dreams of Furiae - a new module for NWN:EE! Buy now
Eye of the Beholder: Enhanced Edition?
Or just straight up Eye of the Beholder IV using 5e rules.
Someone pitch this to WotC already.
Legend of Grimrock 1&2 have paved the way and showed a modern version of a real time grid based dungeon crawler still works and plays great.
The new twist in addition to the obvious modernizations can be co-op multiplayer.
Any players for that?
