Imperium Galactica is a computer game made by a Hungarian company Digital Reality that combines many of the features of 4X games with some of the features of real-time tactical games. The same company would later make its sequel, Imperium Galactica II, in 1999. Imperium Galactica was published and distributed by GT Interactive in 1997. The soundtrack is the work of Tamás Kreiner which was the basis of his reputation. Nexus: The Jupiter Incident, developed by the Hungarian-based Mithis Entertainment, was originally planned and designed as "Imperium Galactica 3" but in development renamed and refocussed to a real-time tactics game.
