In the Florence of the 12th-14th centuries, the city's powerful and influential families don't just compete with each other in trade and politics. They also try to outdo one another by building tall, mostly square-based tower homes as status symbols.
In Firenze, you are master builders working on the families' construction commissions for such towers. Each player competes to earn the most prestige points by completing the commissions from families and the church and by placing their seals on the work they have done. When someone plays their final seal, the other builders get one more turn before the final scoring.
