Galileo's Truth: Secret Treatises (PRE-ORDER)

Secret Treatises is the card expansion for Galileo's Truth – more than 120 new Treatise cards that the publisher describes as doubling the depth of the deck-building game.

Instead of setting up the same standard Treatises every game, Secret Treatises lets you randomise which cards are available on the Treatise boards, so each session presents a different economic and strategic grid to plan around. The new cards span all four subjects – Astronomy, Mathematics, Physics and Philosophy – and many carry two versions of their effect, changing depending on whether you hold the Copernican or Ptolemaic principle. Unlike a modular expansion, it integrates straight into the core game with no new rules to learn.
