Which board game was developed first, Conspiracy or History of the World?
Conspiracy (board game) Conspiracy is a 1973 board game made by Milton Bradley. It can be played by 3 or 4 people, and the main goal is to bring a suitcase to their own headquarters through the use of spies.
Breakthrough (board game) Breakthrough is an abstract strategy board game invented by Dan Troyka in 2000 and made available as a Zillions of Games file (ZRF). It won the 2001 8x8 Game Design Competition, even though the game was originally played on a 7x7 board, as it is trivially extensible to larger board sizes.
