World of Warcraft: Burning Crusade Classic is a substantial expansion for the classic version of the MMORPG, released in 2021, requiring the base game for access. This content transports players to the shattered world of Outland to combat the demonic Burning Legion, introducing a new level cap, new zones, and challenging group content like raids and dungeons. A key feature is the introduction of flight mechanics for navigating the expansive new territories, extending the core RPG progression loop established in the original game.
