Bounded Communities

It is referred to one of the systems of a play community where the players are in a closed system. The community is made from a social play purely within an individual game space and there is no exchange with its outside environment. It exists only within the time and space defined by the magic circle. The play is synchronous with an individual game and the rules of the game have a greater effect on the essence and experience of the community of the game.
