This paper investigates the impacts of individual egoistic and altruistic behaviors in a virtual society built upon the Vidya game, used here as the social simulation and Multiagent System (MAS) platform. The Vidya game was adapted to support Jivas’ (autonomous intelligent agents of the Vidya game) social behavior, including formation of reputations, creation of clans and ‘co’-action based on leadership. The evolving society of Jivas, using the above mentioned social behaviors, becomes an ordered and complex MAS. The experiments carried out demonstrate the impacts of individual altruistic and egoistic behaviors on society and emergence of social order through time as an important and desirable event in open MAS and societies.
