Meuterer is a role selection card game in which players take the roles of crewmembers aboard a merchant ship. Each round, each player reveals goods from their hands that they wish to sell. However, most ports deal in only one sort of goods, and it's the player who's the captain that gets to decide where the ships goes. That's where the mutineer comes in. If a player chooses to become the mutineer, they will try to become captain themself and may change the destination of the ship. Each player may also have an ally in the fight, and the side which played the most conflict points gets the final word on the ship's destination.
Players can score points in various ways. Every time a player sells the most goods out of anyone in one place, or every time a player reaches their destination, either as the captain or as the mutineer, they score points. You also get points if you helped a side win during a mutiny. The player with the most points at the end of the game is the winner.
I liked npetry's English remake of the player aid cards, but it needed a rounds card and a scoring aid card. His file has space for these cards as well. The file name of that file is: meuterer-cards-ltr.zip.
