Funny I've bought most of them with the assumption that I'll be able to use parts of them, new monsters, spells, etc, here and there, but I've used next to zero. Figured Id have learned by now? The only adventures I bought with the specific intentions of running were the Waterdeep and Undermountain ones that came out in 2018. The portion of the Undermountain I read and ran didnt do anything for me so I ended up pretty much just making up my own adventure. I browsed and read parts of the Waterdeep adventure and the same. Just dont have the wherewithal to read, prep and run a 200+ page, 12 month adventure. I really miss the old 16, 32, 64 page adventures. Even the 96 page ones seemed to drag. Anything over 3 or 4 sessions to get through is too long for me. I like to switch things up pretty frequently in my games.
