@aburtch I would say #DungeonCrawlerCarl is great for anyone that grew up playing #WOW #Runsescape #DungeonsandDragons or RogueLike style games. I totally see why its hit or miss.
The books are generally about a guy that gets stuck into an alien show based on leveling up and maneuvering through set-piece dungeons meant to kill them. The fun is when the main character starts exploiting game mechanics to cause chaos and try to enact revenge on the alien hosts.
Its a goofy and fun light read.
