Gameplay



Master of Orion is a turn-based game in which players alternate actions and decisions with computer-controlled opponents. A mouse

 is needed, but hot keys can access many functions.

The main screen is a scrollable map of the galaxy; clicking on a star system makes the rightmost part of the main screen display information about the planet there. If the player has not explored the system, only the word "unexplored" appears; otherwise the panel shows the planet's current and maximum population; if the player has a colony there, it also offers controls to allocate the colony's output.

There is a separate space combat map, and additional screens for managing research, diplomacy and espionage. The diplomacy and espionage screen acts partly as a menu that provides access to screens about specific aspects. There is also a Planets List screen that can be used in managing an empire's economy.

Lockable sliders are used to allocate a colony's output between ship construction, planetary defenses, factory construction, ecology or research. Within each of these industry sectors,there is a fixed sequence of activities to which resources are allocated; for example defense effort will be used to upgrade existing missile bases if improved missile types have been discovered, then to build or upgrade planetary shields, and finally to build additional missile bases. The technology screen uses a similar set of lockable sliders to allocate research spending between the 6 technology areas.

Overview


The game begins with a single colonized homeworld and two scout ships that can be used to explore nearby stars. As the game progresses, new worlds are discovered, other races encountered, worlds colonized and wars fought. Despite their different backgrounds and homeworlds, all races possess legends of the Orions, a master race that once controlled the galaxy, and their protected homeworld containing powerful secrets and technology. The homeworld is found in the Orion star system and is defended by a powerful robotic starship, the Guardian.

Victory conditions


Victory is gained either by eliminating all opponents or by being elected supreme leader of the galaxy at a meeting of the High Council. Elections are held every 25 turns after two-thirds of the planets in the galaxy have been colonized, and each empire's voting strength depends on its population. To be elected High Master, an empire's leader must gain at least two-thirds of all available votes, with abstention
Abstention
Abstention is a term in election procedure for when a participant in a vote either does not go to vote or, in parliamentary procedure, is present during the vote, but does not cast a ballot...

s counting as a vote against both candidates. Some combination of conquest and diplomacy is usually necessary in order to gain such a large majority. Once a High Master is elected the player can accept the result or challenge it; the latter results in a "Final War" that is fought to the death between the High Master's supporters and the dissident.

Despite the game's name, conquering the Orion star system is neither necessary nor sufficient on its own to win the game. The planet in the Orion system is unusually large and extremely valuable, since artifacts

 left by its former inhabitants give its conqueror some very advanced military technologies, one of which players cannot research for themselves, and a colony there will be four times more productive in research than on most other planets. Other races are also more likely to support the empire that holds Orion during High Council elections. In order to colonize Orion or capture its technology one must destroy the robotic Guardian warship, a feat that requires a large, advanced fleet.

Economics


All of a colony's outputs are based on its industrial production

, including research. All citizens are capable of industrial production, but are significantly more productive when assisted by factories. There is a limit on the number of factories a unit of population (notionally 1M individuals) can operate, but players can increase this by researching and building upgrades. The cost of upgrades rises rapidly unless the player first researches technologies that reduce factory costs.

Players can allocate a planet's industrial output to various combinations of: building or upgrading factories; building or upgrading a planet's shields and missile bases; research; spaceship construction; and ecology
Ecology

 (pollution control, terraforming, increasing population growth). A planet's output can also be transferred to the planetary reserve (treasury

), but with a 50% penalty.

The treasury can also be increased by scrapping ships or missile bases, by gifts from other empires and by random donations from non-playable mega-rich individuals. Its funds can be used to boost the output of other planets, subject to strict limitations, and to provide gifts to other empires.

The need to clean up pollution is a serious constraint on economic growth in the early game. Various technologies reduce the cost of cleanup to the point that pollution may not be a significant factor in later stages. Players must also pay maintenance costs for ships, missile bases and spies, which is financed by a percentage tax that is calculated by the software and applied to production at all colonies; players cannot control how this burden is allocated between colonies.

Planets


The software generates a map randomly at the start of each game; the player's only influence over the map generator is the ability to choose the size of the galaxy and the number of AI opponents. Star systems have at most one colonizable planet and a few have none. Planets vary in the following ways:
Mineral wealth Productivity in factory, defense and ship construction
Ultra-poor 33%
Poor 50%
Normal 100%
Rich 200%
Ultra-rich 300%
  • Mineral wealth dramatically influences a colony's industrial productivity when building or upgrading factories, building or upgrading defenses and building ships; it has no impact on the productivity of research nor of ecological improvements such as pollution
    Pollution
    Pollution is the introduction of contaminants into an environment that causes instability, disorder, harm or discomfort to the ecosystem i.e. physical systems or living organisms . Pollution can take the form of chemical substances, or energy, such as noise, heat, or light...

    .
  • Habitability influences population growth rates: fertile planets increase growth rates by 50% and Gaia planets by 100%, while hostile planets halve them. There are seven normal and six hostile planet types; the various hostile types require increasingly advanced technology to colonize, which extends the exploration and colonization phases of MoO for much longer than in most 4X
    4X

     games. Hostile planets are the most likely to be rich or ultra-rich in minerals. All planets can be upgraded to Gaia class with the appropriate technologies.
  • Size, which determines the planet's initial population capacity. This can be more than doubled by various kinds of terraforming.
  • Artifact worlds contain relics of a now-vanished advanced civilization. These usually provide a free technology advance to the first empire that discovers the planet, and double the research productivity of a colony there. On Orion the conquering race receives four technology advances, and the research productivity of a colony there is quadrupled.


At the start of the first turn each player can see the locations of all other stars but only the planet in its home system. Each starts with one colony ship and two scouts.

Technology


The designers regard technology

 as the most contribution to a player's success. Advances can be acquired through research, trading, spying or conquest. Six technology areas can be researched to produce new advances:

  3. Force fields: protective shields for ships, planets and ground troops; devices that make it harder to hit the players' ships; and some special weapons.
  4. Planetology

    s for use by ships, missile bases and ground troops.


If a ship uses a component from a particular technology area, further advances in that area reduce the cost and size of the component; this effect is called "miniaturization". When one has researched all of the technologies in an area of the tech tree, further research can discover "advanced technologies" in that area, which do not provide specific new capabilities but increase the miniaturization of ship components.

Players can research several technologies at the same time, controlling the allocation of research resources by means of lockable sliders on the Technology screen. Each research project returns "interest" on resources invested in it, using a formula that produces the greatest return if the project accounts for 15% of the total research budget. There is a small random element in the number of turns required to achieve an advance – it may take a few more or less than one would predict on the basis of simple arithmetic.

In each game each player is allowed to see a different random subset of the technologies at each level. On the other hand there are often alternative technologies that provide similar benefits. These features force players to adapt rather than follow the same favorite research strategy in each game. One can also make up for any important gaps by spying, technology trading or conquest.

Spaceship design



Ships can be used to colonize planets, scout for planets worth colonizing, attack other races and defend against attacks. Only six ship designs can be used at a time; beyond that, a previous slot must be emptied and all ships of that class scrapped before a new class can be designed. Ships cannot be upgraded or refitted with new technology; the exceptions are discoveries that increase travel or scanning range, which automatically affect all ships.

There are four hull sizes; smaller sizes are harder to hit while larger ships can survive more damage and hold more components. There are eight types of components, each with different effects:
  1. Battle computers increase the chance of a beam weapon hitting and damaging a target
  2. Shields reduce the damage done by opponents' weapons
  3. Electronic countermeasures

  4. Armor determines the amount of damage a ship of a given hull size can withstand before being destroyed
  5. Engines power on-board systems, determine the speed of interstellar travel and a ship's maximum maneuverability during combat
  6. Combat maneuverability determines how fast a ship can move during battle and how hard it is to hit; maximum maneuverability is determined by the engine type used
  7. Weapons: missiles, beams, bombs and biological weapons (these reduce a colony's population without damaging buildings)
  8. Special systems which have varying effects: improve a ship's range or maneuverability; improve weapon accuracy or range; provide defensive, offensive, repair or sensing advantages; a few "special" weapons, some of which affect whole stacks of enemy ships; colony bases are also considered special systems

Space combat and invasions


Ships can travel to any star system within their range and combat always occurs in orbit
Orbit

 over a planet - it is impossible to intercept enemy ships in deep space. All ships of the same class form a single stack, moving and firing as a unit. Players can control space combat manually or ask the software to resolve combat automatically. Battles are almost always decided by numbers and technology rather than by clever tactics. An attacker can bomb a planet during combat and, if it wins the space combat, can bomb more intensively immediately afterwards.

Invading an enemy colony without destroying all defending ships and missile bases will result in the loss of some or all of the invading ground forces before they land, and hostile planets can not be invaded unless attackers have technology that allows them to colonize an at least equally hostile type of planet. There are no specialist invasion ships; invading forces are drawn from the population of one or more colonies, which reduces the population of the planet(s) from which they are sent.

Invasions are depicted in real-time

 of technologies if enough factories survived the attack, and control over a new system that extends the range of the invader's ships. A successful invasion exterminates the previous inhabitants and the surviving troops form the planet's new population.

Races


Players choose to be one of 10 pre-defined races - one cannot create customized races. The Klackons and Meklar have different types of advantage in industrial production; the Sakkra have very fast population growth; the Psilons are the best at research; the Mrrshans and Alkari have different types of advantage in space combat; the Bulrathi are the best at ground combat; the Humans have advantages in trade and diplomacy; the Darloks excel at spying and sabotage; and the Silicoids can colonize even the most hostile planets without any research and are not constrained by pollution, but have slow population growth.

Typically races are very good in one research subject and below average in another. However, the Psilons are very good in all areas, while the Silicoids are above average in computers, which is useful for spying and sabotage, but are weak in all other research areas. The Humans excel in one area, and are good in two others. They and the Sakkra have no weak subjects.

Each race has a pre-defined initial relationship with each other race, and they gradually return to these relationships unless these are improved or damaged by events. Most races start with neutral relationships to most other races, except that each has an uneasy or in some cases belligerent relationship to one other race. The exceptions are the Humans, which initially have amicable relationships with all others, and the Darloks, whose espionage skills make them objects of suspicion to all except the Humans.

The races also have "personalities" which vary from one game to another when played by the AI. Their attitudes to other races can vary from honorable (reliable friend and unforgiving enemy) or pacifist to aggressive or xenophobic
