TradeWorlds: Planetary Expansion is an expansion for TradeWorlds: Exterra Edition released in 2017 for 1–4 players, 60–120 minutes per game, and ages 13 and up. It was designed by Kristopher R. Kycia and its main mechanics are Hand Management, Trading, and Dice Rolling.
Description from the publisher: A "core" set expansion that is designed to increase the level of strategy by adding Tradeships and Trade Agreements. It features the Mission cards that were removed from the original one (1) Player Box Set due to complexity and an attempt to "streamline" the original game for a wider gamer audience. Missions are back and therefore so are Tradeships. Tradeships allow you to perform a mission which may take 1 to 5 turns to complete, during this time the player on a mission will benefit from a Trade Agreement which will give them bonus credits when banking certain resources. Modifiers are 2x, +5 and 3x the value of the banked resource (according to the Trade Agreement). This expansion is comprised of 140 cards for 1 to 4 Players. It also adds 4 white custom dice to be used as counters for Tradeships. It can add from 15-30 minutes of additional game time to the "core" game. However, this is offset by higher banking of resources, which ultimately balances the duration of the game.
TradeWorlds: Planetary Expansion supports 1–4 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 TradeWorlds: Planetary Expansion is 60–120 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 TradeWorlds: Planetary Expansion for ages 13 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.
