For California-based video game publisher Riot Games, it's all about the players. Their proclaimed goal is to become "the most player-focused game company in the world", and with their well-established and rapidly rising popularity in the online gaming scene, this goal doesn't seem far-fetched at all.
Incorporated in 2006, the company is best known for their first and, as of now, only title Leage of Legends (LoL): a multiplayer online video game in which players can form teams and lunge into battle with characters known as "champions", competing against each other to ultimately advance into the opposing team's territory and destroy their "nexus" to win the duel. League of Legends is free to play and has, since its initial release in October 2009, constantly been fit with updates and expansions of the in-game universe. New chooseable champions and skins are added regularly and can be purchased by players via micro transactions and in-game currency for a highly unique and individualized gaming experience. Staggeringly popular all over the world with far over 60 million active players, the game has given rise to a massive number of competitive players in the E-Sports scene who engage in prized events, tournaments and national as well as international championships. Riot Games dedicate most of their time and funds to the further development and enhancement of League of Legends with over a thousand employees constantly working to improve the game and guarantee the highest level of entertainment for its players.
Riot Games are a global company with a variety of outposts in the USA and South America, Europe, East Asia and Australia. They rely heavily on feedback from their fanbase and frequent game conventions to stay in touch with their audience.
