Games die gespeeld worden via het turn-based systeem zien we tegenwoordig niet meer zo vaak voorbij schieten. De vorige delen uit de Master of Orion reeks maakten gebruik van dit systeem, Infogrames neemt het risico niet en gaat in Master of Orion3 verder met het "real-time space combat system". Wat is het doel van de game? Lees en huiver:In MOO3, players a ume the biggest role ever. No longer do players merely represent petty interplanetary dictators. In MOO3, players represent the controlling power behind an entire galactic civilization. The dictators, presidents, councils, and overlords that come and go are merely a player's pawns. One must use these governments and their leaders to secure the destiny of one's civilization and to manipulate its policies of freedom and oppre ion in both foreign and domestic arenas. It is not enough to be an able economist or a great captain to succeed in Master of Orion 3; considerable political, administrative, and espionage skills must be applied to craft your civilization's glorious chapter in the Annals of Time and Space. Vandaag zette de developer de website over de game online waarop veel extra informatie over Master of Orion3 te vinden is, voor een bezoek is deze link beschikbaar.
