Championship Manager 01/02 implemented the new EU regulated transfer system, introduced in September 2001, and also featured a new 'attribute masking' mode, whereby the player could only see information about footballers they would realistically know about (also known as a fog of war). The game sold more than 300,000 copies in the United Kingdom.Īlthough never particularly expanding on the graphical side, Sports Interactive included many new features along with the usual updated database. The game allowed players to take charge of any club in one of around 100 leagues across 27 countries, with responsibility for tactics and signings. It was later released on Xbox in April 2002. It was released for Microsoft Windows in October 2001, and for Mac in November 2001. Championship Manager: Season 01/02 is a football management video game in Sports Interactive's Championship Manager series.
