Multiplayer video game
A multiplayer video game is a video game in which more than one person can play in the same game environment at the same time,[1] either locally on the same computing system (couch co-op), on different computing systems via a local area network, or via a wide area network, most commonly the Internet (e.g. World of Warcraft, Call of Duty, DayZ). Multiplayer games usually require players to share a single game system or use networking technology to play together over a greater distance; players may compete against one or more human contestants, work cooperatively with a human partner to achieve a common goal, or supervise other players' activity. Due to multiplayer games allowing players to interact with other individuals, they provide an element of social communication absent from single-player games.

For other multiplayer games, see Game § Multiplayer.The history of multiplayer video games extends over several decades, tracing back to the emergence of electronic gaming in the mid-20th century. One of the earliest instances of multiplayer interaction was witnessed with the development of Spacewar! in 1962 for the DEC PDP-1 computer by Steve Russell and colleagues at the MIT. During the late 1970s and early 1980s, multiplayer gaming gained momentum within the arcade scene with classics like Pong and Tank. The transition to home gaming consoles in the 1980s further popularized multiplayer gaming. Titles like Super Mario Bros. for the NES and Golden Axe for the Sega Genesis introduced cooperative and competitive gameplay. Additionally, LAN gaming emerged in the late 1980s, enabling players to connect multiple computers for multiplayer gameplay, popularized by titles like Doom and Warcraft: Orcs & Humans.
Online multiplayer[edit]
Online multiplayer games connect players over a wide area network (a common example being the Internet). Unlike local multiplayer, players playing online multiplayer are not restricted to the same local network. This allows players to interact with others from a much greater distance.
Playing multiplayer online offers the benefits of distance, but it also comes with its own unique challenges. Gamers refer to latency using the term "ping", after a utility which measures round-trip network communication delays (by the use of ICMP packets). A player on a DSL connection with a 50-ms ping can react faster than a modem user with a 350-ms average latency. Other problems include packet loss and choke, which can prevent a player from "registering" their actions with a server. In first-person shooters, this problem appears when bullets hit the enemy without damage. The player's connection is not the only factor; some servers are slower than others.
A server that is geographically closer to the player's connection will often provide a lower ping. Data packets travel faster to a location that is closer to them. How far the device is from an internet connection (router) can also affect latency.[12]
Asynchronous multiplayer[edit]
Asynchronous multiplayer is a form of multiplayer gameplay where players do not have to be playing at the same time.[15] This form of multiplayer game has its origins in play-by-mail games, where players would send their moves through postal mail to a game master, who then would compile and send out results for the next turn. Play-by-mail games transitioned to electronic form as play-by-email games.[16] Similar games were developed for bulletin board systems, such as Trade Wars, where the turn structure may not be as rigorous and allow players to take actions at any time in a persistence space alongside all other players, a concept known as sporadic play.[17]
These types of asynchronous multiplayer games waned with the widespread availability of the Internet which allowed players to play against each other simultaneously, but remains an option in many strategy-related games, such as the Civilization series. Coordination of turns are subsequently managed by one computer or a centralized server. Further, many mobile games are based on sporadic play and use social interactions with other players, lacking direct player versus player game modes but allowing players to influence other players' games, coordinated through central game servers, another facet of asynchronous play.[17]
