A number of games support professional competition. The tournaments which emerged in the mid 1990s coincided with the popularity of fighting games and first-person shooters, genres which still maintain a devoted fan base. In the 2000s, real-time strategy games became overwhelmingly popular in South Korean internet cafés, with crucial influence on the development of eSports worldwide. By 2010, multiplayer online battle arena games had become very popular as esports. Competitions exist for many titles and genres, though currently the most popular games are League of Legends, Dota 2, Counter-Strike: Global Offensive, Smite , Hearthstone and StarCraft II. Hearthstone has also popularized the digital CCG genre in the electronic sports community since its release in 2014.
