This game is played by creating a parallel universe with one difference to this one. The next poster will then state the result due to the difference, and make his/her own universe.
Example:
User 1: There is a parallel universe where people greet each other by smashing their knees together.
User 2: As a result, humans are no longer able to walk. There is a parallel universe where men have breasts.
There is a parallel universe where the sky is bright red.
There is a parallel universe where the world would end unless someone correctly determines whether the following statement is true or false withing a hundred years.
As a result, Armor Games is the new Kongregate. There is a parallel universe where multiplayer games don't exist. And I did post a parallel universe. In it you couldn't post parallel universes.
There is a parallel universe where humans don't exist. Sorry for the double post, I've come to associate enter with submit and so I get them confused. Embarrassing.
