Kingdom: Classic is free on Humble Bundle for a limited time.
In Kingdom, each coin spent can tip the balance between prosperity and decay. Attend to your domain, border to border, or venture into the wild to discover its wonders and its threats. Master the land, build your defenses, and when the darkness comes, stand with your people, crown on your head, until the very end.
