What is a Realm?

With millions of people playing World of Warcraft, it is simply impossible for everyone to play together in the same place. This is the reason why the different "realms" were created. A realm is a game world that exists only for the few thousands of players within it. Each realm is exactly the same as any other in terms of the game world, but each realm has its own player characters who are tied to that particular realm. You can interact with all the players on your realm but you cannot interact with players on other realms. Characters also cannot normally move between realms.

Realms are defined by name and type. Choosing your realm is the very first decision you will have to make before playing World of Warcraft. In any case, you can speak with, search for, and group only with other players that have created characters of the same faction (Horde or Alliance) and on the same realm as you. Players on opposite factions cannot talk, group, or trade with each other on any realm; their most meaningful interaction will be on the battlefield.

Gameplay mode vs. realm type

World of Warcraft includes both player vs. environment (PvE) and player vs. player (PvP) gameplay. In PvE gameplay, you can do quests, fight monsters, speak, trade, gain experience, learn skills, and advance levels as you would in any other massively multiplayer online role-playing game (MMORPG). In PvP gameplay, you are fighting other players in the wilderness or in special places called Battlegrounds. Sometimes these two gameplay modes can intersect, for example, when a player is attacked by another player (PvP) while fighting a monster (PvE).

Because players may prefer one type of gameplay over the other, there are different realm types that emphasize or deemphasize certain gameplay elements, such as PvP. However, the core game will the much the same for any realm regardless of type. The differences between the realm types are detailed below.
