Endure, and Realism
Rules-light and focused on ordinary people, the center of Endure as a survival RPG is, quote: “Its Endurance economy. Endurance helps characters succeed and keeps them going, but is always depleting. If you are out of Endurance, you have to rely solely on your cunning and luck of the roll — and often it is not enough to survive. You need time and resources to recover Endurance, so the game ebbs and flows between tense action and quiet downtime.”
