Summary

Understand World of Warcraft factions: Alliance (Humans, Night Elves, Dwarves, Gnomes, Draenei) vs Horde (Orcs, Forsaken, Tauren, Trolls, Blood Elves).

In World of Warcraft, the primary factions are the Alliance and the Horde. The Alliance consists of Humans, Night Elves, Dwarves, Gnomes, and Draenei. The Horde is comprised of Orcs, Forsaken, Tauren (often depicted as bulls), Trolls, and Blood Elves. While often presented as good versus evil, the source suggests that Tauren and Forsaken, and possibly none of the Horde, are not entirely evil.

The distinction between good and evil is less pronounced in PvE (player versus environment) realms compared to PvP (player vs player) realms, where this conflict forms a significant part of the gameplay.

Your choice of faction in World of Warcraft does not fundamentally alter the game's core experience, with differences mainly limited to visual elements and the types of players you will encounter. Questlines remain largely similar and in the same geographical areas for both factions until approximately level 30, when both continents open up more fully.
