The new expansion explores the clash between parliaments, monarchies, and the entrepreneurs in the Nucleum world (see "'Nucleum'"). It introduces a court mechanic, an action that allows players to acquire thalers, action tiles, victory points, and achievement tokens and bolster their income. Also, if players gain control of political parties, they will have a greater scoring potential during the king’s day phase via unique agendas. This expansion also offers up new Experiment boards that add depth to the gameplay.

The expansion with the core game supports one to four players, ages 14 and up, and plays in 60-150 minutes.
