From Wikipedia (http://en.wikipedia.org/wiki/Warcraft:_The_Board_Game):

Warcraft: The Board Game is a board game adaptation of the Warcraft series of computer games, created by Kevin Wilson and released in 2003 by Fantasy Flight Games. It takes elements primarily from Warcraft III: Reign of Chaos, but also incorporates elements from Warcraft III: The Frozen Throne.
Up to four players may play this game, with each player taking on one of the four playable factions from Warcraft III: The Humans, Orcs, Night Elves, and Undead. Team play is also possible, with the Human and Night Elf players forming the Alliance while the Orc and Undead players forming the Horde. Though the game uses a standard setup, scenario-based gameplay is also possible, and sample scenarios and parts required for them are provided with the game.
