The first 20 years of video game developing in Sweden was mostly done by separate individuals. Developing costs increased and industry structure became more complex over time. Mapping the business of Swedish game developing history has been relatively problematic because individuals were spread all over the country working with different platforms in PDP, C64, VIC-20, Amiga and PC. Home computers became the focus for the creativity among often self learned youths who got access during the 1980s.
