Empire Earth is a real-time strategy game spanning human history from prehistoric times through speculative futures. You advance through 14 epochs—starting at stone tools, ending in nanotechnology—by constructing buildings and spending resources. Each epoch unlocks era-appropriate units and tech: archers give way to musketeers, then tanks, then mechs. Older unit types become unavailable as you progress, though existing ones remain on the field. Advancement costs scale upward, but so does resource income. The base game covers prehistory through a near-future Nano Age; the expansion adds a Space Age focused on colonization beyond Earth. Matches hinge on timing your epoch jumps against opponents and adapting armies as the centuries roll forward. Fans of long-arc strategy campaigns where Bronze Age spearmen can theoretically face digital-era drones will find the scope appealing.
