World of Warcraft is the most important MMORPG ever made, and two decades after launch, it remains one of the most content-rich. The game's influence on the genre is incalculable -- quest design, dungeon structures, talent systems, and raid progression all bear WoW's fingerprints across the entire MMO landscape. At its best, WoW offers unmatched collaborative experiences: 20-player mythic raids requiring precise coordination are gaming's ultimate cooperative challenge. The world of Azeroth, expanded across ten expansions, is enormous and filled with decades of accumulated lore. The Mythic+ dungeon system provides endlessly scaling PvE challenge, and PvP arenas reward mechanical skill and strategic thinking. However, WoW carries the weight of its age and business decisions. The subscription plus expansion cost, combined with microtransactions and a token system, creates an expensive hobby. The game has fluctuated wildly in quality across expansions, with some periods driving away large portions of the player base. Time-gating and daily obligation systems can make the game feel like a job rather than entertainment. The new player experience is bewildering, with systems layered upon systems accumulated over twenty years. For dedicated players, WoW remains irreplaceable; for newcomers, the barriers to entry are formidable.
