Level editor would be great. Maybe somebody will make a good game with it. My hopes are low though, seeing the dominating trends on Nexus.
Divinity Original Sin 1/2 had a level editor. One was very weak, the other was very broken, but both had it. Very little came out of it.
Then again, those were less popular games, with less fandom on the IP. Maybe it works the third time around. I also hope. I want my Neverwinter Nights.
I'll be doing some playing with the modding tools when I am done with my vacation for sure.
