This project is the basis for a sequence games based on this and other timelines already available from Chronozoom.com. Anybody can create their own timelines and then use that data to play ChronoPlay. In the near future groups will be able to compete and if required as an assessment tool all the data is available. Data is drawn from ChronoZoom.com database which is being developed by Microsoft Research, Berkley University, and Moscow University. This is a contribution to the Big History Project aspects of which have been supported by Bill Gates.
