Empire Earth is the first title of an acclaimed series of real-time strategy games, bundled with the Art of Conquest expansion pack. The game is based on actual history, starting with the prehistoric age and spanning half a million years. You can essentially create your own civilization by selecting new unit/building bonuses, epoch by epoch. The single-player campaign missions are very true to the events they're depicting, letting you relearn or reenact some of history's most pivotal moments. Technological development ends at the futuristic "Space Age", letting you start off with sticks and stones and end up with tanks and mechs lumbering through the battlefield.
