Anti what?

Anti-X is a board game made by San Francisco State University Professor Ralph Anspach in response to X. The game was originally to be produced in 1973 as Bust the Trust.
The original game begins with the board in a “Xed” state, effectively the “result” of a completed X game. Players take the role of federal “case workers” bringing indictments against each business in an attempt to return the state of the board to a free market system.
