On May 19th Blizzard filed a suit with the Central District of California over the practice of players who create cheats for multiplayer mode in StarCraft II. In particular, the suit names the "ValiantChaos MapHack" as one of, but not the only, hack being targeted by the litigation. The suit claims that the cheats undermine the nature of multiplayer gameplay and "disrupt or impair the online experience for purchasers of the computer game."
The suit targets the programmers behind the hacks, demanding compensation for the copyright infringement inherent in the cheats' modifications of the game. As noted in the BBC report, this lawsuit recalls a similar one from 1990s, wherein Nintendo unsuccessfully sued the creators of the Games Genie, also on the grounds of copyright violation. That lawsuit, however, took place in the days before widespread online multiplayer gaming environments, and it will be interesting to see how much, or how little, this case echoes that one.
