In an interdisciplinary course of the Center for Computational and Theoretical Biology Subproject 2 and the Games Engineering group developed a computer game on aquatic plants at the Institute for Computer Science at the Julius-Maximilians-University of Würzburg. The goal of the simulation game is to impart knowledge about the ecosystem of the Bavarian lakes and the effects of water quality and climate conditions on aquatic plants. Furthermore, an awareness of these ecosystems and the effects of human intervention is to be created.
