Well basically what the title says, really.   I'm in the mood to play some fancy GZDoom maps/wads in the near future but, I don't know what. So, what good WADs/maps made for GZDoom do you recommend?   I already know/heard about Hanging Gardens, Hurt, Verdant Citadel, City of the Damned, Putrefier, Winter's Fury, Paradise, and Dead Air (I've also played the first 3).   I'm looking more for mapsets rather than, say, TCs for GZDoom, but those are also welcome.
