I have run this adventure several times, both for grognards and newbies. Everyone loves it! I think it is actually the perfect intro one-shot:
- It's a little absurd, but still has epic moments of fantasy
- The encounters are built to combine social and combat at the same time, helping to show new players that those do not have be distinct experiences
- Serious players enjoy the very real danger, sillier players enjoy the sheer lunacy of the situation
One aspect that is great for newer DMs is that the layout/traps encourage the party to split up, but it's still easy to run thanks to the maps and room descriptions. Plus the reveal that Mops' imaginary friend is actually real gets a laugh every time.
I cannot recommend this adventure enough and am 100% confident you and your players will have a blast!
