Warcraft 3 is the third game in Blizzard's Warcraft franchise. It is one of the older eSport games but is still played at a professional level with pro tournaments going from time to time. The vanilla version of the game (Reign of Chaos) was released in 2002 and the expansion set Wrath of the Lich King was released in 2003. The game is a real-time strategy game where two players normally battle each other by gathering resources, teching up and training armies.
Although the game has several similarities to Starcraft the main difference is that you also use one to three heroes together with your army to beat your opponent. The army sizes are also smaller in real unit numbers. In addition to this, the players can choose between four different races with different heroes, units and abilities. The races are Human, Night Elf, Orc and Undead.
