Alright I did a lot of research on this and I've came to this conclusion: A lucky guess......
The guy who invented the game was named Steve Jackson and the guy's been making games since 1974
Steve Jackson's game list
That many games written about society he had to get some things right...
His wikipedia page doesn't say anything particularly exciting, either
Steve Jackson Wiki
No one in particular graduated Rice college around the time he did, so i doubt he had insider knowledge..
Not only that, but why? Why would the Illuminati hide their plans in a card game and a cheesy looking one at that?:up
