As the light fades, two games mosey out of town, six shooters on their hips, hats tipped low against the setting sun. Behind them, a ramshackle town; before them a desert, harsh and unforgiving. In each game they will face danger in the wilds, from bandits to vicious animals. In each they will come to the aid of others on a quest of exploration and vengeance. Despite the similarities, however, their stories will have a crucial difference: one will tell us a tale of civilization and safety rising from chaos, the other of the end of freedom at the hands of civilization. Both games will do so not only with moral choices but with the structure of the game world itself.
