Warcraft III: Reign of Chaos

Warcraft III: Reign of Chaos is an RTS released by Blizzard Entertainment in 2002. It features four completely different races, each with a lengthy campaign, a great multiplayer mode with almost perfect balance and a fantastic map editor which resulted in countless maps and mods for the game over the years. The custom games themselves (named after the game type and factor of limitless possibilities) have spawned guilds and third party development groups to further the creation of these games.

The add-on The Frozen Throne (WC3: TFT) added several new units to each race as well as neutral heroes which further improved the balance of the multiplayer and four new campaigns which complete the storyline and serve as a connection to World of Warcraft.
