About the game
Primordial, the first expansion for Planetarium, adds a new frost line to the board, and new cards that allow you to heat and cool planets for extra points at the end of the game. A new Late Bombardment effect clears the evolution track and re-distributes matter around the board, and also creates comets, which can be used as "wild" matter. -description from designer This expansion adds two modules to the base game: Epochs and Frost Line. One or the other or both may be added. Epochs: The solar system begins with no planets. A player may, instead of moving a Matter token or a Planet, create a Protoplanet. Later, a player may play a Proto Evolution card to turn the Protoplanet into a Planet. The first time the Acceleration space is reached, it triggers the Late Heavy Bombardment instead (all the matter on the evolution track fills the empty solar system spaces, and comets may appear. The second time the Acceleration space is reached, Acceleration occurs normally. Frost Line: This line lies between orbits III and IV (it moves in or out if the Red Dwarf or A-Type star are used). The Low, High, and Final Evolution cards of the normal game are replaced by those in the expansion. Planetary evolution now tracks heat and cold markers. If using the Variable star token, players may spend victory points to vary the star's brightness a notch up or down; this moves the Frost Line accordingly.

Questions and answers
Planetarium: Primordial 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 Planetarium: Primordial is 45–60 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 Planetarium: Primordial for ages 10 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.
Planetarium: Primordial has a complexity rating of 2.8 out of 5 from BoardGameGeek players, which makes it a medium-light 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.
