League of Legends
League of Legends is a 2009 multiplayer online battle arena video game developed and published by Riot Games. Inspired by a modified version of Warcraft III called Defense of the Ancients, Riot's founders sought to develop a stand-alone game in the same genre. Since its release in October 2009, the game has been free-to-play, and is monetized through purchasable character customization. The game is available for Microsoft Windows and macOS.
In the game, two teams of five players battle in player versus player combat, with each team occupying and defending their own half of the map. Each of the ten players controls a character, known as a "champion", with unique abilities and differing styles of play. During a match, champions become more powerful by collecting experience points and purchasing items in order to defeat the opposing team. In the game's main mode, Summoner's Rift, a team wins by pushing through to the enemy base and destroying their "nexus", a large structure located within it.
League of Legends received generally positive reviews, with critics highlighting its accessibility, character designs, and production value. The player base's negative and abusive in-game behavior, criticized at release, persists. In 2019, the game regularly peaked at eight million concurrent players, and its popularity has led to various tie-ins, such as music videos, comic books, short stories, and an upcoming animated series. The game's success has also spawned several spin-offs, including a mobile version, a digital collectible card game, and an in-development massively multiplayer online role-playing game.
League of Legends is often cited as the world's largest esport, with an international competitive scene composed of 13 leagues. The 2019 League of Legends World Championship had over 100 million unique viewers, peaking at a concurrent viewership of 44 million, with a minimum prize pool of US$2.5 million. The North American league is broadcast on cable television sports channel ESPN.
