In management (and control) the most important factor is a thorough knowledge of the behavior (properties, dynamics) of the managed object. In technical systems these properties can be (to a sufficient extent) formally described. In the socioeconomic system this can not be done so easily. This is where games of various kinds can convey the "feeling" of the systems behavior in a very instructive way. The two games presented in this working paper are of that kind. They show, at the same time, how one can turn the constantly extending properties of microcomputers into a greater sophistication of the game. Both games carry important messages for those who are in the process of managing common resources. This property should make this working paper useful to a wide community.
