Rome wasn’t built in a day. Neither is your domain. In Kingdom, you ride into a small camp with naught but a bag of coins. Your only means of interaction, as “King” of this wilderness, is to pay people to do work for you—constructing bows, using those bows to hunt for food, building walls, et cetera.
Every night your realm, with its flimsy wooden ramparts, comes under attack by demons. Your villagers valiantly try to hold them off, giving you another day to expand, another day to conquer the wilderness.
It’s one of the most creative rogue-alikes I’ve played, though the game takes a looooong time to get going—a real blow when you’ve sunk hours into your kingdom and then it falls apart, forcing you to start over.
