For each resource type, a player takes the Monopoly card of its type if they have more than half of the total resources of its type in play.
Usually this means you need 3 resources out of 5. Some Fates add resources or scrap them, removing them from play. Two-player games remove resources from play onto ambition boxes.
Monopolies let you hold the matching resource supply. You add resources on Monopolies to ambitions, but you can't spend them. Also, players need your consent to give that resource during Summits.
