When choosing a character to create in World of Warcraft, there are many choices before you. There are ten races and nine classes available, but the game's primary choice when it comes to character creation is the faction you wish to fight for. In addition to borrowing from some of the most storied locations in Warcraft history, the game also shows off many different kinds of environments, such as the lush forests in Ashenvale and Feralas, the snowy mountains in Dun Morogh, the savannah of the Barrens, the plains of Mulgore, and the deserts of Tanaris. Swamps in Un'Goro Crater, jungles in Stranglethorn Vale, farmland in Elwynn Forest, and even deforested hills in Stonetalon Mountains are some more of the many environmental regions you can explore. Terrain that has been vastly altered by magic and the ravages of war also appear in the game. The razed city of Dalaran, encased in a protective magic shell, is a painful reminder of the devastation of the Reign of Chaos, while the infested Eastern and Western Plaguelands are filled with diseased animals and plantlife, courtesy of the Scourge's plague.

The territories and terrain you will be able to explore are vast and varied. This long list of fascinating terrain doesn't even include the underground environments and dungeons of the world. There are dungeons available for all ranges of mid- to high-level players, and offer many rich quests, rewards, and enemies to encounter in the depths below ground. You can join the Horde or the Alliance, and your choice here determines much of what you can and cannot accomplish in the world. You can only group and talk to players in your own faction. You also can only view and befriend players in your faction when using the in-game social commands. The intent is to make you feel like a member of one enormous team, while at the same time setting up the other faction as an enemy or, at best, a rival. Thus, if you wish to play with your friends, you will want to all join the same faction.
