The Cartoon Network and Grigon Entertainment have become the first partnership between an American entertainment company and a Korean game developer to make a worldwide MMO. At least, that's what a press release sent out today by the popular television network claims. The plan is to have the subscription-based game ready for a free download in spring 2008. Mac and Bloo, Ben 10, and other characters from the Cartoon Network will appear in the game. Like other MMOs, this title will have an expanding, persistent world where you can collect items, develop your own attributes, and create your own character. So far, no official title for the game has been announced and few details about the game itself have been revealed. However, the Cartoon Network looks like its in this for the long haul. Today's announcement says that the network plans to regularly add new content to the game "over a span of several years."
