Introversion Software

Introversion Software Limited is a British video game developer based in Walton-on-Thames, England. Introversion is mostly widely known for creating the top-down tycoon management simulation game Prison Architect, which was inspired by Dwarf Fortress and went on to inspire RimWorld. The company was founded in 2001 by three friends, Chris Delay, Mark Morris, and Thomas Arundel, who met as undergraduates at Imperial College London. The company originally labelled itself "the last of the bedroom programmers" due to the trio working out of their homes – they moved into an office when working on their fourth game, Multiwinia. Their first released video game, Uplink, was programmed and designed almost exclusively by Chris, while Mark and Tom handled marketing, materials and the other business elements. Their small initial investment enabled them to buy CD-Rs and printer cartridges. Early copies of the game were handmade. The company was able to fully make back their investment within a few hours of accepting orders. A large community formed, and the team, along with a new programmer Andy Bainbridge, started work on two new games. Darwinia was released to much critical acclaim and was eventually re-released via Steam on 14 December 2005 On 29 September 2006, Introversion Software launched its third game, DEFCON.
