Simis Limited was a development studio especially known for its flight simulator games. It was founded in 1989 by Jonathan Newth and Ian Baverstock and acquired by Eidos in 1995.
In March 1998 there was a management buyout of the company which led to the formation of Kuju Entertainment. Kuju was originally an offshoot umbrella brand, that housed Simis as a flightsim brand. Later the company fully dissolved into Kuju.
