Please idle me; bonus points for a good idling story.
Though I realize that on its own, having to go through the templates and GNDT to idle is already a fair bit of work.
BlogNomic is an online Nomic: a self-modifying game where changing the rules is part of the game. Players make blog posts proposing additions or alterations to the ruleset, discussing and casting votes in the comments: if enough vote in favour, the rules are changed and play continues.
The game has been running since 2003 and resets every month or so. New players are always welcome and can join in at any time.
