Warcraft III: Reign of Chaos (often referred to as War3 or WC3 or RoC) is a real time strategy video game released by Blizzard Entertainment on July 3, 2002 (US). It is the second sequel to Warcraft: Orcs & Humans, and it is the third game set in the Warcraft Universe. An expansion pack, The Frozen Throne, was released on July 1, 2003 (US).

Warcraft III contains four playable races: Humans and Orcs, which had previously appeared in Warcraft: Orcs & Humans and Warcraft II: Tides of Darkness, and the Night Elves and Undead, which are new to the Warcraft mythos.Warcraft III's single-player campaign is laid out similarly to that of StarCraft (another Blizzard game), being told through all four of the game's races in a progressive manner. In the expansion there are two additional races: the Draenei, a race of eredar who are cursed to be abominations, and the Naga, a race of vile serpents and other creatures that come from the depths of the sea. Multiplayer mode allows for play against other people, via the internet, instead of playing against computer-controlled characters as is done in the single-player custom game mode. Due to the dual storylines of the previous Warcraft games, the story can only be understood if using the proper storylines of one of the campaigns in the previous games, being the Orc Campaign on Warcraft: Orcs & Humans and the Human Campaigns on both the Warcraft II: Tides of Darkness and Warcraft II: Beyond the Dark Portal.

The game proved to be a best seller and one of the most anticipated and popular computer game releases ever, with 4.5 million units shipped to retail stores and over one million units sold within a month.Warcraft III won many awards including "Game of the Year" from more than six different publications.

Warcraft III: The Frozen Throne is a real-time strategy computer game developed for Microsoft Windows, Mac OS and Mac OS X by Blizzard Entertainment. It is the official expansion pack to Warcraft III: Reign of Chaos, requiring Reign of Chaos to play. Released in stores worldwide in multiple languages beginning on July 1, 2003, it includes new units for each race, a new neutral race, four campaigns, five neutral heroes (an additional neutral hero was added April 2004 and two more were added in August 2004), the ability to build a shop and various other improvements such as the ability to queue upgrades. Sea units were reintroduced; they had been present in Warcraft II but were absent in Reign of Chaos. Blizzard Entertainment has released patches for the game to fix bugs, add new features, and balance multiplayer.

Has a great variety of games, but recently one clan has pretty much blitzed the custom game section with a ton of bots making it harder to find those games you really want.
This game also comes with a world editor, making it possible to create your own games and edit scripts n what not for your own enjoyment.

I recently reinstalled this game, it was a lot of fun back in the day, but WCII is probably still my favorite from the series.
