 Unlike most RTS, you are not controlling units, but focus on high-level
 strategic planning: Building infrastructure, securing resources, and moving
 your armies. The core game mechanics turns out to be quite close to WWI-WWII
 type of warfare, however, there is no explicit reference to any
 historical period.
