Personally I can't stand to run a D&D game as players take it all too seriously.
I will run Toon, Call of Cthulhu or Paranoia any day, the latter without a scenario as I can kill off their all their clones in my very dangerous Alpha Complex and have them rolling on the floor laughing the whole time with a help of a stack of prerolled character sheets and some random encounter tables. (I'd expect an LLM to be able to do the same)
Contrast that to the famous Bloodstone campaign which is the pinnacle of D&D scenarios but can't really be challenging to the players because players have to win over and over again if you're going to use most of the material.
I DM for early teens and I would kill for a D&D party that took it all too seriously. :)
