New America
This jar exists because some rules of cooperation are easier to test in fiction first.
New America is a role-playing game in development — a cassette-futurism world set in the America of one hundred years from now, where small townships rebuild cooperation from the wreckage and write their rules down as they go. Tape decks and CRTs survived; the invisible rules didn't, so the people in this world are doing what we're doing on the rest of this site: codifying a culture — except theirs is fictional, which means we get to break it on purpose and watch what holds.
In development, in the open — lore and playable pieces will land here as they're ready.
