History and Purpose of the ICGA

Renamed into the ICGA in 2002 [3] , the association now more broadly fosters the Computer Games community through its relationships with Computer Science, Commercial and Game organizations throughout the world. The ICGA's broader scope reflects the more general way in which computer-game capability contributes to Artificial Intelligence and to the human experience of game-playing.


Robert Hyatt

Robert Hyatt, 1997 in a rgcc post [4] :

I was there when Barend Swets (Believe the spelling is correct) proposed forming this organization in 1977 in Toronto. I was one of many that stood up and said "yes, I'll join." However, others stood up and said I'll not only join, I'll help for nothing, and the ICCA was formed, and continues to work this way. 

Jaap van den Herik

Jaap van den Herik in 2001 in The Bell Captain [5] :

In 1977, the ICCA was founded during the Second World Computer-Chess Championship in Toronto. The organisation was the brainchild of Barend Swets and many participants supported the idea, among them Ken Thompson who then tied for 4th place amongst 16 participants with his program BELLE. CHESS 4.6 won the title but Ken received credit for BELLE's KQKR endgame play against IGM Walter Browne (Fenner, 1979) [6] [7] . Further, Ken agreed to serve as Secretary and Treasurer of the new organisation alongside Ben Mittman, the first ICCA President, and did so successfully and with much enthusiasm for six years.
