Walden, a game, is a first person simulation of the life of American philosopher Henry David Thoreau during his experiment in self-reliant living at Walden Pond. The game begins in the summer of 1845 when Thoreau moved to the Pond and built his cabin there. Players follow in his footsteps, surviving in the woods by finding food and fuel and maintaining their shelter and clothing. At the same time, players are surrounded by the beauty of the woods and the Pond, which hold a promise of a sublime life beyond these basic needs. The game follows the loose narrative of Thoreau's first year in the woods, with each season holding its own challenges for survival and possibilities for inspiration. The audience for the game is broad: from experimental game players to lovers of Thoreau and Transcendental literature. As such, the game offers more opportunities for reflective play than strategic challenge.
