The importance of having a working virtual economy within an MMOG is increasing as they develop. A sign of this is CCP Games hiring the first real-life economist for its MMOG Eve Online

 to assist and analyze the virtual economy and production within this game.

The results of this interaction between the virtual economy, and our real economy, which is really the interaction between the company that created the game and the third-party companies that want to share in the profits and success of the game. This battle between companies is defended on both sides. The company originating the game and the intellectual property argue that this is in violation of the terms and agreements of the game as well as copyright violation since they own the rights to how the online currency is distributed and through what channels. The case that the third-party companies and their customers defend, is that they are selling and exchanging the time and effort put into the acquisition of the currency, not the digital information itself. They also express that the nature of many MMOs is that they require time commitments not available to everyone. As a result, without external acquisition of virtual currency, some players are severely limited to being able to experience certain aspects of the game.

The practice of acquiring large volumes of virtual currency for the purpose of selling to other individuals for tangible and real currency is called gold farming. Many players who have poured in all of their personal effort resent that there is this exchange between real and virtual economies since it devalues their own efforts. As a result, the term 'gold farmer' now has a very negative connotation within the games and their communities. This slander has unfortunately also extended itself to racial profiling and to in-game and forum insulting.

The reaction from many of the game companies varies. In games that are substantially less popular and have a small player base, the enforcement of the elimination of 'gold farming' appears less often. Companies in this situation most likely are concerned with their personal sales and subscription revenue over the development of their virtual economy, as they most likely have a higher priority to the games viability via adequate funding. Games with an enormous player base, and consequently much higher sales and subscription income, can take more drastic actions more often and in much larger volumes. Blizzard Entertainment

 are not afraid to publicly announce that tens of thousands of accounts have been banned due to violations regarding currency selling. This account banning could also serve as an economic gain for these large games, since it is highly likely that, due to demand, these 'gold farming' accounts will be recreated with freshly bought copies of the game.

Comparing MMOGs to other games

There are a number of factors shared by most MMOGs that make them different from other types of games. MMOGs create a persistent universe where the game continues playing regardless of whether or not anyone else is. Since these games strongly or exclusively emphasize multiplayer gameplay, few of them have any significant single-player aspects and the artificial intelligence

 on the server is primarily designed to support group play. As a result, players cannot "finish" MMOGs in the typical sense of single-player games.

Most MMOGs also share other characteristics that make them different from other multiplayer online games. MMOGs host a large number of players in a single game world, and all of those players can interact with each other at any given time. Popular MMOGs might have thousands of players online at any given time, usually on a company owned server. Non-MMOGs, such as Battlefield 1942

 or Half-Life usually have fewer than 50 players online (per server) and are usually played on private servers. Also, MMOGs usually do not have any significant mod

s since the game must work on company servers. There is some debate if a high head-count is the requirement to be an MMOG. Some say that it is the size of the game world and its capability to support a large number of players that should matter. For example, despite technology and content constraints, most MMOGs can fit up to a few thousand players on a single game server at a time.

To support all those players, MMOGs need large-scale game worlds, and servers

A game server is a remotely or locally run Server used by game clients to play multiplayer video game. Most video games played over the internet operate via a connection to a game server....
 to connect players to those worlds. Sometimes a game features a universe which is copied onto different servers, separating players, and this is called a "sharded" universe. Other games will feature a single universe which is divided among servers, and requires players to switch. Still others will only use one part of the universe at any time. For example, Tribes (which is not an MMO) comes with a number of large maps, which are played in rotation (one at a time). In contrast, the similar title PlanetSide

-like areas of the game to be reached via flying, driving, or teleporting.

MMORPGs usually have sharded universes, as they provide the most flexible solution to the server load problem, but not always. For example, the space sim Eve Online
EVE Online

Eve Online is a video game by CCP Games. It is player-driven persistent-world massively multiplayer online game set in a science fiction space setting....
 uses only one large cluster server peaking at over 51,500 simultaneous players.

There are also a few more common differences between MMOGs and other online games. Most MMOGs charge the player a monthly or bimonthly fee to have access to the game's servers, and therefore to online play. Also, the game state in an MMOG rarely ever resets. This means that a level gained by a player today will still be there tomorrow when the player logs back on. MMOGs often feature ingame support for clans and guilds. The members of a clan or a guild may participate in activities with one another, or show some symbols of membership to the clan or guild.

However, the boundaries between multiplayer online games and MMOGs are not always as clear or obvious. Neverwinter Nights

Technical aspect

It is challenging to develop the engines that are needed to run a successful MMO with millions of players. Engines include Graphical, Physical and Network engines. Most developers have done their own, but attempts have been made to create middleware

, software that would help game developers concentrate on their games more than technical aspects. An example of such an engine is the one from BigWorld

BigWorld Technology is a middleware platform for the development of Massively Multiplayer Online Role-Playing Games and virtual worlds. It was developed by the Australian game development and technology company, Micro Forte....
, which recently signed a contract with Cheyenne Mountain Entertainment to deliver the engine for their production of Stargate Worlds .

An early, successful entry into the field was VR-1 Entertainment whose Conductor platform was adopted and endorsed by a variety of service providers around the world including Sony Communications Network in Japan; the Bertelsmann Game Channel in Germany; British Telecom's WirePlay in England; and DACOM and Samsung SDS in South Korea . Games that were powered by the Conductor platform included Fighter Wing, Air Attack, Fighter Ace, EverNight, Hasbro Em@ail Games (Clue, NASCAR and Soccer), Towers of Fallow, The SARAC Project, VR1 Crossroads and Rumble in the Void.

One of the bigger problems with the engines has been to handle the vast amount of players playing the games. Since a typical server can handle around 10-12000 players, 4-5000 active simultaneously, dividing the game into shards (servers) has up till now been the solution. This approach has also helped with the latency issues (delays, hacking etc.) that many players experience due to limitations of the internet. Another difficulty, especially relevant to realtime simulation games, is time synchronization across hundreds or thousands of players. Games like Fighter Ace , Aces High and Warbirds must rely on time synchronization to drive their physics simulation as well as their scoring and damage detection.

Real-world simulations

Some MMOGs have been designed to accurately simulate certain aspects of the real world. They tend to be very specific to industries or activities of very large risk and huge potential loss, such as rocket science, airplanes, battle tanks, submarines etc. Gradually as simulation technology is getting more mainstream, so too various simulators arrive into more mundane industries.

The initial goal of World War II Online
World War II Online

World War II Online: Battleground Europe, also referred to as WWIIOL:BE, WW2OL or BE is a massively multi-player online first-person shooter Video game first released June 6, 2001....
 was to create a map (in north western Europe) that had real world physics (gravity, air/water resistance, etc), and ability for players to have some strategic abilities to its basic FPS/RPG role. While the current version is not quite a true simulated world (lacking details such as weather), it is very complex and contains the largest persistent world of any online game.

The MMOG genre of air traffic simulation is one example, with networks such as VATSIM and IVAO
IVAO

IVAO may refer to:* Ivao Group - a volcano located in the southern part of Urup Island, Kuril Islands, Russia* International Virtual Aviation Organization - an online flight simulation network...
 striving to provide rigorously authentic flight-simulation environments to players in both pilot and air traffic controller roles. In this category of MMOGs, the objective is to create duplicates of the real world for people who cannot or do not wish to undertake those experiences in real life. For example, flight simulation via an MMOG requires far less expenditure of time and money, is completely risk-free, and is far less restrictive (fewer regulations to adhere to, no medical exams to pass, and so on).

Another specialist area is mobile telecoms operator (carrier) business where billion-dollar investments in networks are needed but marketshares are won and lost on issues from segmentation to handset subsidies. A specialist simulation was developed by Nokia called Equilibrium/Arbitrage to have over a two day period five teams of top management of one operator/carrier play a "wargame" against each other, under extremely realistic conditions, with one operator an incumbent fixed and mobile network operator, another a new entrant mobile operator, a third a fixed-line/internet operator etc. Each team is measured by outperforming their rivals by market expectations of that type of player. Thus each player has drastically different goals, but within the simulation, any one team can win. Also to ensure maximum intensity, only one team can win. Telecoms senior executives who have taken the Equilibrium/Arbitrage simulation say it is the most intense, and most useful training they have ever experienced. It is typical of business use of simulators, in very senior management training/retraining.

Others

A large number of games categorize under MMOBBG (BBG meaning Bulletin Board Game; very similar to MMOBBRPGs), having the entire game primarily made up of text and descriptions, although images are often used to enhance the game.
