Players control a character from either the first- or third-person perspective and begin exploring the world, completing quests, interacting with other characters, and fighting all sorts of monsters from the WarCraft universe. The game has several different realms or servers that are independent of one another. The realms include a player-versus-environment (PvE) mode, in which players complete quests and fight against AI-controlled characters; a player-versus-player (PvP) mode where players not only have to contend with monsters but also other player characters; plus two variations on the PvE and PvP where players role-play different scenarios. World of Warcraft’s frequent updates and expansions have helped maintain its popularity, making it the most renowned MMORPG in history. There have been seven expansions updating nearly every aspect of the game, from gameplay to graphics. The expansions include The Burning Crusade, Wrath of the Lich King, Cataclysm, Mists of Pandaria, Warlords of Draenor, Legion, and Battle for Azeroth.

Guild Wars 2 does not have traditional expansions like World of Warcraft, but rather adds “seasons” of Living Stories, which can be compared to WoW expansions. The game is free to download, but the free version does not contain as much functionality as the full release.
