„System Blue“ aims to sensitize the player to the problems of distributing scarce water resources in less developed countries. It puts the player in charge of supplying various consumers with the precious liquid. But not all of them can be supplied at the same time. Consequently, the player must ensure a fair and sustainable water distribution by controlling valves that redirect it to each demanding party. Timing is of great importance, because whichever water tank overflows or runs dry is lost.
