The rule could be anything, as funny or as serious as you want. The universe will progress in a similar way that it has up until this point, unless your changed rule prevented it from doing so.

Some examples might be:

  • The invention of currency is not allowed.
  • Iron is slightly less stable.
  • The Ancient Greeks are able to cultivate Silphium, which does not go extinct now.
  • Blastboom Strice@mander.xyz

    Haha thanks :)

    And yeah, this could probably quickly either wipe us out (along with possibly everything else) or help us flourish (along with the rest of the world)
