Master of Orion 3

Master Of Orion 3 MAC CD command ships space empire building alien war RTS game! 







After a six year break, Master of Orion returns in its third incarnation. This 2003 version of the classic empire-building game expands upon many of the factors that made the original and its first sequel so popular, offering bigger maps, a greater variety of ships, and a more robust tech tree. Large galaxies can hold over 250 different star systems that contain as many as eight planets each. Individual planets themselves may support multiple moons, offering lots of space and resources for new colonies. The game also features advancements in artificial intelligence, especially concerning diplomacy and combat tactics. Many of the alien races and themes familiar to veterans of Master of Orion and Master of Orion II return in this edition.

Breaking from tradition, ship combat occurs in real-time here, though in a manner designed to integrate naturally with the rest of the turn-based gameplay. Unlike most straight RTS games, the Master of Orion 3 players' battlefield influence is more strategic, less tactical. Instead of the continuous quick-click direction and redirection of individual units, the player may rely on the AI of individual ship captains to make good tactical choices, each according to its particular situation. Command adjustments and new orders may also be given in the heat of battle, as needed. Each ship has its own experience and statistics that affect its individual performance, but ships group together into task forces and it's at this level of organization that most orders are given and executed. Players head into battle with fleets that may consist of many task forces.

Since the early stages of the game's design, Quicksilver's vision was to retain the style of the classic MicroProse games while adding more thorough governing options and bringing a deeper level of detail to the many different aspects of galactic conquest. The player sets the empire's basic policies and goals in the game, then a legion of AI governors helps ensure that these are properly implemented at all levels of exploration, production, and warfare. Though designed to be a rare necessity, detail-minded gamers can also choose to micromanage nearly any individual aspect of the empire. Players thus take customized control of the actions and affairs of diverse planets, ships, and personnel that might flourish across an interstellar realm spanning many parsecs.

For Mac [*Please review compatibility/platform sections in 'What You Get']


This item is for the original media, and includes only the media (ie. CD, floppy ...) UNLESS specifically stated above and/or in the title. If more than just the media is included, it will state which items are (ie. box, manual, etc ). Items that come in a sleeve refer to a generic CD sleeve (typically white) and will be sent with shipping protection to avoid damage during transit. If available, we will also send the front and/or back CD inserts if in stock. If these are important to you, please message us to verify we have them available to send. Please do not assume items are included other than what's stated. Again, ask questions PRIOR to purchasing if you have any concerns.


All images/pictures are stock photos and are for reference only, mainly to show the type of game you will be getting. Please read "WHAT YOU GET" for what is included with the media. Screenshots may vary based on your own computer system, video card, monitor, etc.


Computers are like people, each one is different. Unlike console games, a computer game may install and work flawlessly on one system but may need adjustments on another. This is due to a variety of factors, mainly the OS platform running, video card you have, drivers, protection software installed, etc. Many times manufacturers release updates to games to fix bugs and add enhancements. We would be happy to help get the game going on your computer, but ultimately compatibility issues are the responsibility of the buyer. We suggest going to Google and searching for the name of the game along with the words "system requirements" to determine if your system is suitable. Ultimately, we are not responsible for software compatibility problems or publisher's errors.


Stated within the auction is what platform the game will work on (ie. Windows, Mac, Linux...) This is a generic statement and specific platform versions (ie. XP, Vista...) will have to be researched by the buyer. Games that came out PRIOR to XP or higher will not specifically state they will work on that release, but only because they came out before those versions were made. Many, if not most, will work on XP or higher with a few quick adjustments. We provide instructions with all items purchased on how to do this adjustment using the Program Compatibility Wizard. If we find out that an item will definately not work on a specific version, we will state it. For DOS games, you may need to play it with a free DOSbox program if the Program Compatibility Wizard does not work.

64-Bit Windows OS Systems:
For 64-bit Operating Systems, older games most likely will NOT work due to 64-bit systems not being able to run 16-bit programming code (most games prior to 2000). For DOS games, you may need to play it with a free DOSbox program.

Macintosh Systems:
For Macintosh programs, most older games will need to be run in Classic Environment if you have a MAC OS X 10.0 - 10.4 version. Please research Google on how to do this, or send us a message for information prior to purchasing. If your MAC OS system doesn't support Classic Environment (ie. MAC OS X 10.5 or Higher OR Intel Macs), you will have to try running it using the free program called SheepShaver, but compatibility is not ensured. Please research prior to purchasing or ask questions.


Please verify you have the required hardware in order to use the specified media (ie. CD, DVD, floppy drives, etc.) If the item comes as a floppy disc, make sure you have either the needed 3.5" floppy drive or the bigger and older 5.25" floppy drive.


  • Ask questions PRIOR to purchasing an order to avoid any confusion.
  • Be patient if there are problems during installation or gameplay. Typically someone else has already ran into that problem and has listed a solution online. Contact us and we will do our best to help.
  • Be sure to update your video card drivers and search for updates to the game from the manufacturer.
