Andrew Nicholas Oliver and Philip Edward Oliver, together known as the Oliver Twins, are British twin brothers and video game designers.

They developed computer games while they were still at school, contributing their first type-in game to a magazine in 1983. They worked with publishers Codemasters for a number of years following their first collaboration Super Robin Hood, creating the Dizzy series of games and many of Codemasters' Simulator Series games. In 1990 they founded Interactive Studios which later became Blitz Games Studios. In October 2013 they founded Radiant Worlds,^[2] based in Leamington Spa, with long time friend and colleague Richard Smithies.

Philip and Andrew Oliver first began programming computer games while at school (Clarendon School in Trowbridge^[3]). They discovered their interest in computing when their brother bought a used ZX 81 when they were 13. They bought a faster Dragon 32 in September 1982, with a bigger memory. They tried to improve the type-in games they found in magazines and eventually created their own game, Road Runner, which was published as written code in Computer and Video Games Magazine in January 1984.^[4][5] The same year they won first prize in a national TV competition (The Saturday Show) to design a computer game.

Both of the Olivers take an active role in supporting the UK games industry. Philip Oliver is one of the founders of developers' trade body TIGA and has served as an active board member (currently a director) since its inception in 2001.^[16] He was also a director on the board for e-skills UK for several years.^[17]

The brothers received honorary doctorates in 2008 from Coventry University (in business administration (DBA) and technology (DTech) for Philip and Andrew respectively) in recognition of their contribution to the growth of the electronic games industry both regionally and internationally,^[6] and were honoured as Fellows of the Royal Society of Arts in 2010.^[18]

After Philip attended the launch of the UK Government's Next Gen Report (also known as the Livingstone-Hope Report) in February 2011 about challenges faced by the UK Games industry, he established Made in Creative UK ^[19] which with Andrew they run as a not for profit campaign to raise awareness of the world class game developers and digital creatives developers based in the UK. The campaign has over 350 supporting companies and many high-profile supporters, including Sajid Javid MP (Culture Secretary & Secretary of State for Business, Innovation and Skills).^[20]

The Oliver Twins' early games and story inspired many people to develop video games as a career, and this was captured in Chris Wilkins and Roger Kean's book Let's Go Dizzy: The Story of the Oliver Twins,^[21] published December 2016 through Fusion Retro Books.

A video shot at the launch of the book entitled Videogame Legends – Computerphile^[22] prompted Markus "Notch" Persson, the creator of Minecraft, to tweet that he was one of those inspired by the Oliver Twins games: "I grew up loving and being inspired by their work."^[23]

In December 2017 Guinness World Records awarded the Oliver Twins the record for "Most Prolific 8-bit videogame developers". They developed 26 different commercially released games for 8-bit computers and consoles from 1984-1992 and wrote a total of 49 games overall, taking into account titles released for multiple platforms.^[24]
