It is my opinion that DOS2 is the peak of the CRPG resurgence and (obviously) the most popular of them (although Baldur's Gate 3 may take that crown) - but there is no way that it started it.
I will say that having loved the old school CRPGs (Fallout and Fallout 2 are probably in my top 10 games ever, plus I enjoyed the BG games and such as well) I thought they were dead and gone. DOS2 revived my interest in them and Wasteland 3 drove that interest even higher, to the point where I went back and played most of the newer ones. The only ones I can't get into are the Owlcat ones as they strike me as buggy messes.
Also, as a note on this... now that Bethesda, Obsidian and inXile are all owned by Microsoft I hold out hope that one day we will get an old school, turn based Fallout game. If it was done right I think it would probably be my most anticipated game ever made.
