By some estimates, the economy of World of Warcraft is worth $200 million, while Second Life's economy has been recently valued at $64 million. Everquest generates so much in the way of economic value that its GDP has been rated at around $2600 per capita. Lots of that value comes from real-life buying and selling of virtual-life assets, like skills and items for characters, or the characters themselves. Many gaming aficionados make a modest living doing just that -- the IRS has even opined on the subject, so it must be worth something.

Wherever that economy takes place, it won't be on eBay anymore. Starting this week, eBay Inc. (NASDAQ:EBAY) has been delisting auctions for virtual property, in a move that many say is a ploy to avoid legal battles with the games' owners. They're using the IP excuse: the auction site already has a policy in place that sellers can't trade in a product unless he is "the owner of the underlying intellectual property, or authorized to distribute it by the intellectual property owner." While game players may be in possession of a certain skill, or have spent their good money and countless hours to develop a character, they don't "own" that in the legal sense -- all the IP rests with the company which created the game.

So auctions like this and this will soon be ended. Many game players don't seem too concerned, though; as Eliah Hecht says on WOW Insider, "all this will probably do is stop individual users from selling their accounts. Gold farmers, powerlevelers, and other secondary industries have their own sites, and presumably will not be hindered much by this." I'd love to have seen eBay's cost-benefit analysis on this one!
