Professional gamers generally play video games for prize money or salaries. Such individuals usually deeply study the game to master it and usually to play in competitions.[30] A pro gamer may also be another type of gamer, such as a hardcore gamer, if he or she meets the additional criteria for that gamer type. In countries of Asia, particularly South Korea and China, professional gamers and teams are sponsored by large companies and can earn more than US$100,000 a year.[31] In 2006 Major League Gaming contracted several Halo 2 players including Tom "Tsquared" Taylor and members of Team Final Boss with $250,000 USD yearly deals.[32]
