World of WarCraft is a game made of many parts: resource gathering, combat, item-creation... and some of those parts are more fun than others. A company called MDY wanted to help with the dull bits of the game, and maybe assist gold farmers a little bit, by releasing a program called Glider that allows your character to continue collecting gold and leveling while you're not at your computer. In 2006, Blizzard and Vivendi showed up at an MDY employee's home and threatened legal action against the company, claiming Glider violates the Terms of Service of World of Warcraft as well as the Digital Millennium Copyright Act. MDY then sued to establish its right to sell its software, causing Blizzard to file its own suit to stop MDY from selling the program. The issue is whether or not Glider is breaking any laws, and Blizzard is hoping that by stretching the boundaries of what constitutes copyright infringement, it can get MDY shut down. If Blizzard succeeds, it could set a very dangerous precedent.
