  Indonesian traditional villagers have a tradition for the sake of their own
social and economic security named 'nyumbang'. There are wide variations of the
traditions across the archipelago, and we revisit an observation to one in
Subang, West Java, Indonesia. The paper discusses and employs the evolutionary
game theoretic insights to see the process of 'gantangan', of the intertwining
social cohesion and economic expectation of the participation within the
traditional activities. The current development of the gantangan tradition is
approached and generalized to propose a view between the economic and social
sphere surrounding modern people. While some explanations due to the current
development of gantangan is drawn, some aspects related to traditional views
complying the modern life with social and economic expectations is outlined.
