Which game was the first title played in the Overwatch League?

Overwatch was the first and only game played in the Overwatch League. Blizzard Entertainment launched the league in 2018 as a city-based professional competition built around its team-based hero shooter.

The inaugural season began in January 2018 with twelve franchise teams. Unlike a multi-game esports organizer, the Overwatch League was created specifically for competitive Overwatch, so its title and league name referred to the same game.

Overwatch uses teams of heroes with distinct abilities and roles. Professional matches originally centered on objective-based maps and a structured team format, which made roster composition, ultimate-ability timing, and coordinated strategy especially important.

A common confusion is between Overwatch and Overwatch 2. Overwatch 2 replaced the original game as the competitive platform in later years, but the league began with the original Overwatch and was founded around that first title.
