[NOTE: I originally wrote this review back in 2023 as a guest post for Bones of Contention, a critic collective comprised of many of the best RPG bloggers out there. This review is a little old, but I stand by it!]
Jim Henson's Labyrinth: the Adventure Game is a self-contained system and adventure adapted from the 1986 film Labyrinth, published in 2019 by River Horse Games. The main creators behind it are the brothers Jack and Chris Caesar, but the adventure is mostly written by Ben Milton (AKA Questing Beast). The book is 294 pages and uses the original concept artwork for the movie by Brian Froud, with additional artwork by Ralph Horsley and Johnny Fraser-Allen.
I own the PDF of the game and am currently running it for the second time, both campaigns using Discord voice+text and Roll20 as a VTT. As probably indicated by the fact that I'm running it again, I am a big fan. Short review: 10/10, quite likely the finest experience I've ever had using published RPG material at my table. But this book already has a lot of positive reviews, and I felt like it might be worth it to spotlight some of the qualities that I haven't seen discussed in those. The things which I didn't really discover until I played it myself.
[By the way, the artwork in this post was done by my friend Norn, a groovy firey whose face was stolen by the Goblin King. You can find their stuff and contact them about commissions at norn-noszka.com]
