Imperator is an Alternate Earth game, one set in a future world where Ancient Rome never fell. Small changes at crucial moments in Roman history create an entirely new timeline for Earth, leading to a star-spanning Roman Respublica and thousands of years of interstellar Pax Romana. The Republic is home to many planets, each containing wildly different flora, fauna, creatures, culture, and climate. As the game begins, new threats to the Republic have sprung up internally and from beyond its borders, making the galaxy more dangerous and the Republic itself less stable - an exhilarating setting for the online gamer. Over the last few decades, many themes of classical Roman history have found their way into modern science fiction and fantasy, in Imperator the architecture, beauty, nobility, and even the savagery of Rome are the heart of the game.
