Chan began his game development career while he was still employed as a programming consultant on an airline sales system. He released a strategy game based around competing program managers at a television station in the early 1990s. This propelled him to undertake the game that would eventually become Trevor Chan's Capitalism in 1995. He also became interested in developing a real-time strategy game, inspired by adapting the empire-building aspects of Sid Meier's Civilization into real-time. The end result was the release Seven Kingdoms. He produced sequels to both Capitalism and Seven Kingdoms, and has plans to follow up with further releases in the series.
