The Creative Assembly is a British video game developer established in 1987 by Tim Ansell and based in the West Sussex town of Horsham. An Australian branch is also operated from Fortitude Valley, Queensland. In its early years, the company worked on porting games to DOS from Amiga and ZX Spectrum platforms, later working with Electronic Arts to produce a variety of games under the EA Sports brand. In 1999, the company had sufficient resources to attempt a new and original project, proceeding to develop the strategy computer game Shogun: Total War. Shogun: Total War was highly successful for the Creative Assembly and is regarded as one of the benchmark strategy games. Subsequent titles in the Total War series built on the triumph of Shogun: Total War, increasing the company's critical and commercial success.
