"SimCity" inspired a new genre of video games. "Software toys" that were open-ended with no set objective were developed trying to duplicate "SimCity"'s success. The most successful was most definitely Wright's own "The Sims", which went on to be the best selling computer game of all time. The ideas pioneered in "SimCity" have been incorporated into real-world applications as well, as urban developers have recognized that the game's design was "gamification" of city planning by integrating numerous real-world systems for a city or region interacted to project growth or change. For example, VisitorVille simulates a city based on website statistics. Several real-world city improvement projects started with models inspired by "SimCity" prior to implementation, particularly with the onset of more-connected smart cities.
