congratulate the opponent, win or lose, on a "good game, well played". Many video games have also inspired internet memes and achieved a very large following online. The culture of online gaming sometimes faces criticisms for an environment that can promote cyberbullying, violence, and xenophobia. Some are also concerned about gaming addiction or social stigma. However, it has been argued that, since the players of an online game are strangers to each other and have limited communication, the individual player's experience in an online game is not necessarily different from playing with artificial intelligence players. History The history of online games dates back to the early days of packet-based computer networking in the 1970s, An early example of online games are MUDs, including the first, MUD1, which was created in 1978 and originally confined to an internal network before becoming connected to ARPANet in 1980. Commercial games followed in the next decade, with Islands of Kesmai, the first commercial online role-playing game, debuting in 1984, as well as more graphical games, such as the MSX LINKS action games in 1986, the flight simulator Air Warrior in 1987, and the Famicom Modem's online Go game in 1987.

Following improvements in connection speeds, more recent developments include the popularization of new genres, such as social games, and new platforms, such as mobile games. Entering into the 2000s, the cost of technology, servers, and the Internet has dropped so far that fast Internet was commonplace, which led to previously unknown genres like massively multiplayer online games (MMOs) becoming well-known. For example, World of Warcraft (2004) dominated much of the decade. Several other MMOs attempted to follow in Warcrafts footsteps, such as Star Wars Galaxies, City of Heroes, Wildstar, Warhammer Online, Guild Wars 2, and Star Wars: The Old Republic, but failed to make a significant impact in Warcrafts market share.
