Warhammer Fantasy Battle was a tabletop war game created in the 80s. It has a fantasy theme, but its real appeal is in how well it manages to mix seriousness and silliness. Like, there can be flying dinosaur people fighting rat men with magic gatling guns, as well as Holy Roman Empire guys with rocket launchers and tanks, and Arthurian knights, each one of them having their own culture, history, and motivations, and it works as a world. Its lore is developed into the point that it would appeal to the kind of person, upon being asked what they think of medieval history, would ask "which century"?
