One of three or more communication devices is selected as a parent node, whereby communication delay that affects the advancement of an interactive task such as a multiple-player participation game is reduced. A game system 100 has a large number of game devices 10. Game device 10 is grouped with two or more other devices to form a group, in which one device becomes a provisional parent node, and the two devices become provisional child nodes. Each of the game devices 10 that are in a group generates measurement data indicating the sum of response times with respect to other game devices 10 with itself as an origin. Game device 10 that has generated measurement data indicating the minimum sum will be a parent node, and the other game devices 10 will be child nodes. A child node communicates with another child node via a parent node.
