How to Play Behold: Rome

About Behold: Rome, from BoardGameGeek:

Behold: Rome is a solo civilization-building card game played without a table. Store and spend resources to develop your civ and build your engine. Conquer wealthy regions, or abandon them to level up your nation. Outsmart and outscore your chosen rival civ to solidify your place in history! Cards have 4 orientations, called levels. Every card level is unique and has its own (often conditional) scoring rule. Your goal is to orient your deck for maximal scoring, upgrade your nation card, and conquer the wealthiest regions by the end of round 12! Every turn, you will play cards to take actions. You will store and spend two different resource types: materials (typically spent to upgrade cards) and population (typically spent to conquer regions). Conquer actions let you take control of regions, which boost your production engine. You may need to abandon regions, however, to develop your nation or gain valuable tributaries. Your nation card has 4 levels, each with a powerful and unique scoring ability. You start as a monarchy, but can progress to a republic, empire, and even a theocracy! -description from the designer
