About the game
Key Market is the sixth game in the Key series of stand-alone games published by R&D Games set in the medieval lands of Keydom, with components in both English and German. The game is designed by David Brain, who was a playtester on some of the earlier Key games. The game is the first game published by R&D Games that has not been designed by Richard Breese. Richard this time takes on the role of developer and the game consequently has the same look and feel as the previous Key games, with artwork again by Juliet Breese plus its own set of ani-/vegi-/arti-meeples. Each player controls an extended family of workers. Over the course of two years, players will organise their workers in an attempt to turn their initial scanty resources into a thriving economic system. After an initial set up phase, the game is played over eight seasons. Each season has three distinct phases, during which players may take a variety of actions. The topography, weather, and seasons will influence the ability of workers to produce crops and livestock in the fields and luxuries in the villages. In addition, resources and luxuries may be bought and sold in the market, or gold and favours sought and acquired. Other workers may be sponsored to join the powerful guilds, where they will acquire skills as they gain promotion to become craftsmen or even the guild master. Turn order throughout the game is determined by the player’s position on the season track, which changes at the end of each season. At the end of the game, the player who has acquired the most gold will win the game. David Brain’s designer notes on the box sides conclude by stating that ‘Key Market is a reasonably intricate game. Some of the strategies that can be employed (particularly the effective use of the market) are not immediately apparent, and some of the Guild combinations do not look so devastating at first glance. But for those looking for a challenging medieval resource management/economic engine game, here you are.’ The game is for two to four players, with a game time of approximately 30 minutes plus 30 minutes per player. Key Market was released at the Essen Spiel in October 2010 as a limited edition of 900 copies. The game was reprinted in 2019.

Questions and answers
Key Market supports 2–4 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Key Market is 90 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Key Market for ages 12 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Key Market has a complexity rating of 3.5 out of 5 from BoardGameGeek players, which makes it a medium-weight game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
