From English Wikipedia:
Superior Software (a.k.a. Superior Interactive) is a video game publisher. It was established in 1982 by Richard Hanson and John Dyson, two graduates of the University of Leeds, England. They had previously programmed software published by Micro Power, and they wrote Superior's first four game releases for the BBC Micro: three were written by Hanson and one by Dyson.
Superior initially focussed on the machines of Acorn Computers Ltd; and key management personnel have included Steve Botterill, Chris Payne and Steve Hanson.
Major software developers Peter Johnson, Tim Tyler, Martin Edmondson, Nicholas Chamberlain, Kevin Edwards, David Hoskins, Matthew Atkinson, Chris Roberts, Tony Oakden, Peter Scott, Gary Partis, Peter Irvin, Jeremy Smith, David Braben, Ian Bell, Geoff Crammond, Jonathan Griffiths and Nick Pelling have all produced software published by Superior, sometimes released under the joint Superior Software / Acornsoft brandname.
Superior, under the brandname Superior Interactive, now mainly develops and publishes software for computers running Microsoft Windows; and they have released several updated versions of their popular 1980s hits for that operating system.
Their most well-known games are the Repton series of games, which sold over 125,000 units for the Acorn Computers.
