Seeing as we are all doing "[insert game here] is the only correct answer", I'd like to double down on NWN2 OC being the only correct answer. Not only is it terrible, it's also terribly long. They improved like 3 things from the original but somehow made everything else worse or equally awful (while somehow focusing almost exclusively on the campaign instead of the toolset).
So, what exactly are you saying is better in DS3 compared to NWN2?
Story? Combat?
Really, when you think about it NWN2 is better in almost every way, apart from general bugginess and engine efficiency of course. And those have been largely fixed with patches.
BTW, NWN2 OC >> NWN1 OC. That's a really shitty campaign right there. NWN1 was the game that put me off Bioware - the last Bioware game I ever bought.
