If you’re too slow, you miss out on the gold those tents would provide. For example: Right at the start, there’s a small window to build three tents before the next round of income arrives.

Your build order will vary slightly, but there are some things you’ll want to do no matter what. Just like any RTS, an efficient start is paramount. Wood, Stone, Iron, and Oil operate more traditionally - your buildings keep generating them, and they’ll stockpile forever. That stockpile has a maximum number (depending on how many warehouses you have), and anything above that is either wasted or automatically sold at the market. You’ll always have the same amount of energy until you make another mill, or power plant, and you won’t run out of energy until you build something that saps it. Food, energy and workers are resources that stay static until you build again.
