The witness seminar ”Svensk dataspelsutveckling, 1960–1995” was held at Tekniska museet [the National Museum of Science and Technology] in Stockholm on December 12, 2007 and was led by Mirko Ernkvist. The participants were Swedes that had been involved in the development of computer games during this period. The development process of several pioneering computer games were discussed from the perspective of the developers themselves. These games included: a demonstration game on the Saab manufactured computer D2 (1960–61), Stugan (1978), Space Action (1983), Fairlight (1985), Time Zero (1985), several games by Team17 (1990–) and Backpacker (1995). Computer game development efforts were initiated early in the Swedish history of computing, even by international comparisons. The first known Swedish game with moving graphics was a demonstration game for D2 displayed on an oscilloscope from the early 1960s. When computers became more widespread among Swedish universities, game development efforts soon followed. The first Swedish adventure game, “Stugan” was released in 1978 on the computers at Stockholm Datacentral, QZ. Subsequently, the introduction of home computers in Sweden in the early 1980s enabled more widespread Swedish game development efforts. Many Swedish game developers from this time were self-learned, but several were also involved in some of the computer groups that emerged during this time. These groups cracked, compressed, modified and traded computer games and created demos. The cracker and demo culture of the 1980s provided an environment of learning, socialization, and competition for many Swedish game developers. England that had a more established computer game industry during the 1980s provided opportunities for some of the Swedish game developers. The game “Fairlight” by a Swedish developer was published by an English game company and another Swedish game developer was one of the founders of the English game company Team17. Other Swedish game development projects discussed such as “Space Action”, “Time Zero” and “Backpacker” had Swedish companies as publishers.
