Back when I started playing Doom again I had a bunch of review sites bookmarked with the express intent of finding obscure but memorable stuff on the larger end of the scale. One of these was Geniac's Doom WAD Playlist. The descriptions aren't very thorough but they give you a brief picture. One of the interesting PWADs that I wasn't able to locate on the archive was CASTHENG by "James XIII". Back when the entry was made it was logged as consisting of fourteen "tough scary castle levels". After I sent out a feeler in 2012 in the "Trying to Find a Specific WAD" thread on Doomworld, The Mad Butcher delivered and provided me with a copy. I was surprised to discover that Castle of the Hengs had been further developed to the point of replacing MAP01-MAP30 of Doom II.
