1975 in video games

1975 saw several critical influences in the history of video games, including the first commercial games utilizing large-scale integrated circuits and microprocessors, as well as the first role-playing video games.

On the back end of the Pong boom, the coin-operated video game industry achieved new expressions of gameplay and animation in arcade games. Racing games and competitive shooting games became particularly popular. Local multiplayer games accommodating more than four players were released by Atari, featuring advanced implementations of transistor-transistor logic hardware. Several games utilizing microprocessors debuted in coin-op, including the influential Gun Fight from Midway Mfg.

The console industry saw its first competitive environment in the United States with Magnavox, Atari, and smaller competitors introducing systems utilizing advanced circuit designs. Atari’s Pong home console featured a sophisticated custom chip created in-house.<ref name=":03" /><ref name=":0" /> European dedicated consoles remained isolated to specific regions, but offered some of the first console lines from companies like Videomaster. Japan’s first native console was developed and released by toy company Epoch.

Computer networks saw a mass proliferation of game variants written in the BASIC programming language which influenced the emerging field of microcomputers. Games introduced in publications like People’s Computer Company and 101 BASIC Computer Games were frequently played via teletypes on time-sharing connected terminals; some were distributed via the remote connected ARPANET. The PLATO network likewise experienced a massive uptick in titles following the popularity of Empire and Spasim. Midwestern universities connected to the PLATO system were early recipients of the spread of Dungeons & Dragons, which prompted several student groups to develop the earliest computer role-playing games.

Most popular arcade games

RePlay magazine published its first popularity chart for coin-operated games in the United States in March 1976, covering games of the previous year. The lists were based on polling operators regarding their opinions of games receiving the most attention in their locations.<ref name=":1">Template:Cite journal</ref> RePlay's charts were based only on a subset of operators and are not on imperial metrics such as earnings reports, but they give a strong indication of games which were of the most value to arcades and street locations.

The RePlay rankings included both video and electro-mechanical games which ran in close competition through the 1970s until video games became dominant. Outside of the top twenty ranked in order, forty-eight other games were also listed.<ref name=":1" />
