One of the most repeated and touted inspirations for Sid Meier's Civilization is the earlier Avalon Hill board game of the same name, designed by Francis Tresham for Hartland Trefoil in Britain. While Meier had no doubt heard of the game prior to 1990 through his connections with Bruce Shelley, he insists that the influence is not as strong as some claim. "I had not played that before I did Civilization," says Meier. "I played it later. I remember there were some cards and trading. It was more ancient; it didn't really come into any sort of modern or medieval times."
But connections, however thin, were there: Bruce Shelley had not only worked for Avalon Hill, the American publisher of Tresham's Civilization, but he created the American localization of Tresham's 1929 railroad game, a game which served as an admitted inspiration for Meier's earlier Railroad Tycoon. It should come as no surprise, then, that Shelley was intimately familiar with Tresham's Civilization. "I had played it many times," recalls Shelley. "I believe Sid had a copy of the game and looked at the components. I owned the original board game, but don't recall if I brought it into the office."
