Esports is a competitive activity based in modern multiplayer video games. Similar to traditional sports, esports requires that athletes achieve a monumental mastery of their chosen game. Esport games represent a wide variety of competitive genres such as real-time strategy (RTS) and first-person shooter (FPS). Typically, athletes specialize in a specific genre, often playing a single game for their entire career. Major tournaments for these games boast massive global viewership and revenue, frequently exceeding those of many traditional sports.
