World of Warcraft

World of Warcraft is an extremely popular MMORPG, and before that a real time strategy game. In its MMO form, it is an RPG set in a fantasy world called Azeroth.

Gameplay
Player characters in Azeroth are split into two major warring factions: the Alliance and the Horde. The Alliance is made up of six "good" races: Dwarves, Draenei, Gnomes, Humans, Night Elves, and Worgen. The Horde is composed of six "evil" races: Blood Elves, Forsaken, Orcs, Tauren, Trolls, and Goblins. "Good" and "evil" are used ironically here because none of the races are truly good or evil: they all have good and bad qualities, and members of the Horde are just as apt to see the Alliance as the bad guys as vice versa.

During character creation, the player chooses one of the above ten races and one of ten classes (though not all classes are available for all races): Death Knight, Druid, Hunter, Mage, Paladin, Priest, Rogue, Shaman, Warlock, Warrior. Character appearances are highly customizable, usually including hair style and color, facial features, skin color, and distinguishing features like facial hair, tusks, or horns. All races have male and female options.

In gameplay, the character interacts with various NPCs, who give them tasks, called quests, to do. This can be as simple as talking to another NPC or killing a certain number of common monsters, or it can be a difficult quest chain involving many tasks spread out over the map. When a quest is completed, the character is rewarded with experience points, gold, and items. When a character gains enough experience points, they go up a level, giving them access to more and better abilities for their class and allowing them to adventure in more dangerous places in the world.

While characters can travel freely around most of the world, some special areas are separated from the rest, accessible only by portals. These areas are called instances, and they are usually more dangerous (and therefore more rewarding) than their surroundings. Most instances are so dangerous, in fact, that it may take more than one character to survive them. This is where it becomes useful to team up with other player characters in a group. A group of more than five is known as a raid, and some instances are made specifically to be tackled by raids.
