In Monumental, each player will control a civilization that will evolve through his city: a grid of 3x3 cards (coming out from the player's starting civilization deck) that can each be activated to gather various resources such as Science, Military, Production, Culture, and Gold that will allow them to trigger many actions. But there's a trick: one cannot activate all their cards at once, which means that tough choices will have to be made each turn in order to select the cards that are the most needed.
