This USA Today story reports that comic book company Marvel Enterprises is suing NCSoft and Cryptic Studios, saying their MMORPG City of Heroes violates Marvel copyrights. The company particularly isn't too pleased with the ability to create Hulk and Wolverine- like characters in the game.

Marvel claims the firms' are responsible because the game is played on servers operated by the companies, raising the question of whether a company is responsible for their customers' actions on its computer server. Marvel also claims the companies have disrupted its "existing and future" business prospects for licensing its characters in video games similar to City of Heroes.
