Concept: Two survivalists spend 21 days naked in the woods for pretty much no reason.

Political system: Survivalists work together to find food, water, and shelter with only one tool of the modern world, vying for the grand prize of $0 and not dying. There is no social class, no capital accumulation, no ideology, no politics, no voting — just two modern hunter-gatherers pooling their resources to survive the forces of nature.

Is it free and fair? Is man vs. nature ever truly fair?

Concept: Contestants struggle to survive for 39 days in the wilderness for $1 million.

Political system: Players spend much of the game divided into two “tribes” that they are periodically forced to cull by blind vote. Later, the players compete as individuals, and elimination decisions are made by a jury consisting of previously voted-off players.
