The "White Sandbox" campaign of New York Red Box is a mashup of The Caverns of Thracia and The Lost City, run with OD&D. It seems pretty cool.
Absolutely loved the Caverns but I have DM'd it in around 30 years. My memory of it so hazy now but I kind of remember the players fleeing from death (Thanatos?) in one section. We had a blast from what I recall.
My very favorite recap is here:http://www.thealexandrian.net/creations/talesfromthetable/tale04-odnd-thracia.htmlEnjoy! I did.I got the 3.5 version that Necromancer Games did. Very interesting. I look forward to running it. I can't get my hands on the original.
By the way, I love the myconids, the Horror on the Hill, and I came by way of my delight with the Meatshield generator. Keep up the great work!
I've long wanted to run the Caverns of Thracia. Thanks for the link to the Alexandrian recap, fictivefantasies.
