Wow Gold -- Battle.net

Battle.net is an online gaming service used for its games Diablo, Starcraft, Starcraft: Brood War, Diablo II, Diablo II: Lord of Destruction, Warcraft II: Battle.net Edition, Warcraft III, and Warcraft III Expansion Set: The Frozen Throne. It was released in January 1997 coinciding with the release of Diablo. It functions as a way to play over the Internet, featuring cooperative and player-versus-player game playing, a game matchmaking system, and online chat among other features. Battle.net is free, and only requires an Internet connection and account registration in order to use.

A group of gamers reverse engineered the network protocol used by Battle.net and Blizzard games, and released a free (under the GNU GPL) Battle.net emulation package called bnetd. With bnetd, a gamer is not required to use the official Battle.net servers to play Blizzard games.

In February 2002, lawyers retained by Blizzard threatened legal action under the Digital Millennium Copyright Act against the developers of bnetd. Blizzard games are designed to operate online exclusively with a set of Blizzard-controlled servers collectively known as "Battle.net". Battle.net servers include a CD key check as a means of preventing software piracy.

Despite offers from the bnetd developers to integrate Blizzard's CD key checking system into bnetd, Blizzard claims[cite this quote] that the public availability of any such software package facilitates piracy, and moved to have the bnetd project shut down under provisions of the DMCA.[citation needed] As this case is one of the first major test cases for the DMCA, the Electronic Frontier Foundation became involved, for a while negotiations were ongoing to resolve the case without a trial. The negotiations failed however, and Blizzard won the case on all counts: the defendants were ruled to have breached both StarCraft's End User License Agreement (EULA) and the Terms of Use of Battle.net.[citation needed]

This decision was appealed to the Eighth Circuit Court of Appeals, which also ruled in favor of Blizzard/Vivendi on September 1, 2005.
