$330k for Virtual Property

Has anyone heard of Entropia Universe? I have, a while ago, during research for my master's thesis but I never thought it to be very interesting.
Well, seems I was wrong - on Dec 28th last year, a space station in the virtual world of Entropia Universe sold for 3.3 million Project Entropia Dollars (PED.) What makes this number so surprising is that PED can be traded for US dollars at a fixed 10:1 exchange rate. That means that the player with the handle Buzz Erik Lightyear paid $330,000 for a piece of virtual property, a new record high for virtual currency transactions.
