Teams of players compete against each other with the goal of taking down the opposing team's base. The game has been praised for its character designs, accessibility, and high-quality production. Despite ongoing challenges with in-game player behavior, LoL has a substantial player base, reaching a peak of eight million concurrent players in 2019. Moreover, LoL has established itself as the world's leading esport, featuring a competitive scene that leads to an annual world championship event.
