"My kingdom for a horse," yelled Richard III, and I bet he felt like a fool when he realized he'd been doing it wrong all along—the peasants want coins, not horses.
Kingdom is a roguelike-style game where your goal is to expand your kingdom and protect it from monsters. But you're lazy, so you just ride back and forth on your horse all day collecting taxes and then pay people to do the hard work for you. "Build a stockade." "Build a watchtower." "Build a place for people to sleep." "Chop down these trees."
It's good to be king, even if your kingdom is five people, a couple of tents, and a wooden fence.
