Space Harrier (Japanese: スペースハリアー , Hepburn: Supēsu Hariā ) is an arcade video game developed and released by Sega Enterprises in December 1985.
 Originally conceived as a realistic military-themed game played in the third-person perspective and featuring a player-controlled fighter jet, technical and memory restrictions at the time resulted in Sega developer Yu Suzuki redesigning it to fit a fantasy setting centered around a jet-propelled human character.
 Critically praised for its innovative graphics and gameplay, "Space Harrier" is often ranked among Suzuki's best works and considered the first successful entry in the third-person and rail shooter game genres.
 It has made several crossover appearances in other Sega titles and inspired clone games by various developers, while PlatinumGames director Hideki Kamiya cited it as an inspiration for his entering the video game industry.
Wizard of Wor is an arcade game released in 1980 by Midway.
 Up to two players fight together in a series of monster-infested mazes, clearing each maze by shooting the creatures.
 The game was ported to the Atari 8-bit family, Commodore 64, Atari 2600, and Atari 5200 and renamed to "The Incredible Wizard" for the Bally Astrocade.
Play Meter is an American trade magazine focusing on the coin-op and arcade game industry.
 It was founded in December 1974 by publisher and editor Ralph C. Lally II and it is published in physical form by Skybird Publishing on a monthly basis.
 "Play Meter" has published several bi-monthly and annual special issues throughout its history and it maintains a website where online content is also published monthly.
 The magazine is generally regarded as the premier trade magazine of the American video game industry and as the earliest example of video game journalism, establishing such practices as individual video game reviews and the ten-point assessment scale for video game reviews.
The video game industry in the Czech Republic has produced numerous globally successful video games such as and the subsequent ArmA series, the Mafia series, Truck Simulator series, the Samorost series and others.
 There were 300–400 video game developers and around 30 video game companies focusing on video game development in 2014.
 In 2017 it was 1,100 developers and 47 companies.
 Video games are also considered by some experts to be the country's biggest cultural export.
 The video game industry did not enjoy a good reputation and was unsupported by the state until 2013, when the Ministry of Industry and Trade started to seek ways to kickstart the economy.
 By 2014, programs were planned to support the video game industry.
 Another problem is a lack of video game development specialization at any university.
Sega is a video game developer, publisher, and hardware development company headquartered in Tokyo, Japan, with multiple offices around the world.
 The company has produced home video game consoles and handheld consoles since 1983; these systems were released from the third console generation to the sixth.
 Sega was formed from the merger of slot machine developer Service Games and arcade game manufacturer Rosen Enterprises in 1964, and it produced arcade games for the next two decades.
 After a downturn in the arcade game industry in the 1980s, the company transitioned to developing and publishing video games and consoles.
 The first Sega console was the Japan-only SG-1000, released in 1983.
 Sega released several variations of this console in Japan, the third of which, the Sega Mark III, was rebranded as the Master System and released worldwide in 1985.
 They went on to produce the Genesis—known as the Mega Drive outside of North America—and its add-ons beginning in 1988, the Game Gear handheld console in 1990, the Sega Saturn in 1994, and the Dreamcast in 1998.
Gun Fight, known as Western Gun in Japan and Europe, is a 1975 arcade shooter game designed by Tomohiro Nishikado, and released by Taito in Japan and Europe and by Midway in North America.
 It was the first video game to depict human-to-human combat, while the Midway version was also the first video game to use a microprocessor.
 Following its November 1975 release in North America, it went on to sell over 8,000 arcade cabinets in the United States.
 It was ported to the Bally Astrocade video game console as a built-in game in 1977 as well as several home computer platforms.
Video gaming in France is one of the largest markets in Europe.
 The French government give special tax breaks to video game companies.
 In 2014, the French diplomatic service released a report which calculates the profit generated by the French video game industry at €2.7 billion.
 It states that there are 300 video game companies in France.
 It estimates the number of jobs directly related to the video game industry at 5000.
 It estimates the number of indirect jobs created by the video game industry at 10,000.
 The report found that in 2013, around 8 out of 10 people had played a video game in the last 12 months.
Sega Games Co., Ltd. (Japanese: 株式会社セガゲームス , Hepburn: Kabushiki gaisha Sega gēmusu ) , originally short for Service Games and officially styled as SEGA, is a Japanese multinational video game developer and publisher headquartered in Tokyo, Japan, with offices around the world.
 Sega developed and manufactured numerous home video game consoles from 1983 to 2001, but after financial losses incurred from its Dreamcast console, the company restructured to focus on providing software as a third-party developer.
 Sega remains the world's most prolific arcade producer, with over 500 games in over 70 franchises on more than 20 different arcade system boards since 1981.
The Astrocade is a second generation home video game console and simple computer system designed by a team at Midway, at that time the videogame division of Bally.
 It was marketed only for a limited time before Bally decided to exit the market.
 The rights were later picked up by a third-party company, who re-released it and sold it until around 1984.
 The Astrocade is particularly notable for its very powerful graphics capabilities for the time of release, and for the difficulty in accessing those capabilities.
