Many simulation games, such as those in the Microsoft Flight Simulator series, have clans that follow similar patterns to other genres. Notable types of simulation clans include virtual airlines (VAs) and Virtual Military Organizations (VMOs). A virtual airline is a dedicated hobby organization that uses flight simulation to model the operations of an airline. VAs generally have a presence on the Internet, similar to a real airline. It has been proposed that there are over 100 VAs of significance currently active, with tens of thousands of participants at any one time.
