Guardians of Middle-earth incorporates the standard elements of a typical multiplayer online battle arena (MOBA) game, with a strong emphasis upon team coordination. Up to ten players may split into two teams of five and from a pool of thirty-six guardians from The Lord of the Rings franchise, including Gandalf, Sauron and Radagast,^[3] and coordinate to win matches by destroying the opposing team's base.^[4] Unlike most other MOBA titles, Guardians of Middle-earth emphasizes home console, rather than desktop, gameplay, in order to gain a "cinematic" experience.^[5]
