Awesome.Game designer Jason Rohrer was challenged to create a game that was also a religion. As with any good game, or any good religion, it came with a set of straightforward rules. Just plug the flash drive containing his creation into your USB port and follow these steps.
1. Run Chain World via one of the included “run_ChainWorld” launchers.
2. Start a single-player game and pick “Chain World.”
3. Play until you die exactly once.
-3a. Erecting signs with text is forbidden—your works must speak for themselves.
-3b. Suicide is permissible.
4. Immediately after dying and respawning, quit to the menu.
5. Allow the world to save.
6. Exit the game and wait for your launcher to automatically copy Chain World back to the USB stick.
7. Pass the USB stick to someone else who expresses interest.
8. Never discuss what you saw or did in Chain World with anyone.
9. Never play again.
He basically made a little mod for Minecraft that took on a life of its own.
