During the game, you play in two different timelines: the present and the past. In the present, you commission the missing parts of the Requiem from other composers in order to complete it. When developing past events, the game takes place in five epochs in which you contribute by buying new compositions from the composer to sell or exhibit, accompany him on the different journeys through the main courts and theaters in Europe, and gather the resources you need in order to support the musician during his career. During the game, you play cards from a limited hand that you will improve as the game progresses. These cards can be played either as actions or as resource generators, and players need to optimize their resources and finances in order to support their best version of the story and their relationship with Mozart.
