Any nation could send up to three players for any individual (1v1) game and up to two teams for any team game. This is the only restriction directly imposed by WCG, with the only other restriction being expense. Some nations may have more funding available and some may choose to concentrate more players into fewer games; it is the respective national organizer's prerogative.
Each nation held its own national qualifier. Both the format used in the qualifier and the number of players sent to WCG are listed below. For detailed information about a qualifier, click the respective country's name.
