This game is based on the public domain game "Mau Mau", which is basically the same as "Crazy Eights", but it has some twists: There is always a location card active providing an ongoing special rule (the location will change several times during a game), and the Palantir card is not played to the discard pile, but in front of a player and can be stolen by other players for extra points at the end. This set can be combined with the Free Peoples set. Or each can be played on their own. The two are not just reskins of each other. They actually have different rules (while sharing the basic Crazy Eights mechanism). Few minions in film history are as iconic as those from "The Lord of the Rings", and with Herr der Ringe Mau Mau: Mordor Sauron, Saruman, Grima, and a horde of Orcs and Uruk-hai can now settle their differences.
