World Cup Soccer (ワールドカップサッカー), is a football game developed and published by Sega in 1989. It was subsequently brought to the Sega Master System by Sega and various home computers by Elite Systems in the following year. World Cup Soccer has been marketed under many names. In Japan the Mega Drive version has always been known as 'World Cup Soccer and in United States, World Championship Soccer (although some earlier cartridges erroneously use the simplified development name, Soccer on the title screen). In Europe, however, the game was originally sold as a joint venture between Sega, Spanish firm Olivetti and Virgin Mastertronic, becoming World Cup Italia '90, holding the Italian 1990 FIFA World Cup license for a short period. Later variants in Europe are simply titled Sega Soccer.
