INTERVAL
A world that runs on rules, not servers.
What is this?
Interval is a small online world in the spirit of early-2000s browser games: chop trees, catch fish, burn half of them on a campfire, fight goblins, trade with whoever is standing next to you. Every 600 milliseconds the world advances one interval, and everything that ever happens, happens on one.
The difference is underneath. There is no game server. The rules are written in a public constitution, every player's computer enforces them independently, and anyone whose world disagrees with the rules is simply ignored by everyone else. Nobody can shut it down, charge for it, or change it out from under you. An update you don't like is just a different world you don't have to move to.
No company, no servers, no subscription. The world runs on the computers of the people playing in it, and stays alive as long as anyone cares.
Your character is a cryptographic keypair on your machine. No account, no password reset, no one to confiscate it.
There is no official look. This site's client is one window among many, the same world renders in a terminal, in ASCII, or in whatever anyone builds.
The rules never ask whether a player is human. Automation is priced into the economy instead of policed, but presence cannot be automated.
