I got a copy of this a month or so ago, from The Liching Hour. I watched them work on this on their stream and over the years in different formats. This book distills the Viva La Dungeon experience into a solo format and gives you a similar feeling to playing the board game or online (Twitch) version.
It is, at its essence, part Choose your own adventure, part Table Top RPG, and part game show. It has a lot of unique quirks to it and pulls from some of the best practices in these genre's.
It has a decent amount of replayability as there are different goals and rooms that your character can see depending on your choices and dice rolls.
Buy with confidence.
