MOBA stands for Multiplayer Online Battle Arena, which is a subgenre of strategy video games in which two teams of players compete against each other on a predefined map. MOBAs are a fusion of real-time strategy (RTS), role-playing, and action games, and they have many elements of preexisting genres while still offering unique gameplay. In general, the design philosophy of the MOBA genre has moved away from constructing structures, army building, and controlling additional units in favor of hero-centric gameplay. Some key features of MOBAs include control over one specific character in a party, growth in power over time, learning new thematic abilities, leveling and accumulation of experience points, usage of the mana resource, equipment and inventory management, completing quests, and fighting with powerful boss monsters. MOBAs are typically five-on-five team games where each player controls a single hero with unique skills and abilities, and the ultimate goal is to destroy the enemy base. Some of the most popular MOBAs include League of Legends, Dota 2, and Smite.
