Master of Orion (MoO or MOO) is a critically acclaimed turn-based, 4X science fiction computer strategy game released in 1993 by MicroProse on the MS-DOS and Mac OS operating systems. The purpose of the game is to lead one of ten races to dominate the galaxy through a combination of diplomacy and conquest while developing technology, exploring and colonizing star systems. The game was developed to run under MS-DOS or Mac OS.
Two sequels were created, Master of Orion II: Battle at Antares in 1996 and Master of Orion III in 2003 - as well as the free, open source FreeOrion which is loosely based on the series. A prototype was developed under the name Star Lords though it was only released as freeware in 2001 as part of the promotion for MoO III.
