"Walden, a game" recreates Henry David Thoreau's experiment to live in a cottage in the woods near Concord, Massachusetts.
At the start of the game, the cabin is just a skeleton frame, allowing for views of trees and the occasional scurrying or flying animal.
The real Walden Pond has changed little since Thoreau lived there. Visitors can swim there but not camp overnight.
The map in Thoreau's video game journal has GPS. It marks where you are in relation to fixed objects.
Communing with nature, the game reminds you, can restore inspiration.
Thoreau lived very simply, with just a bed, desk and single chair for furniture.
In the game, as in Thoreau's life, walking to Concord is needed to get mail and supplies.
There are plenty of activities available, but you must perform odd jobs to make money for food and supplies to endure, especially in winter.
You can visit Thoreau's friend, the essayist Ralph Waldo Emerson, and talk to him and do odd jobs for money.
The game's creator, Tracy J. Fullerton, argues that "Walden, a game" creates "an immersive experience that slows us down, gives us time and permission to contemplate and reflect, and, perhaps, bring that slower pace back into our own busy lives where we can."
Communing with nature might be the most enjoyable part of the game: being still, watching the wind sway flowers and branches, glimpsing a chipmunk, hearing an owl and stargazing at night.
