In 2009, Jon Jacobs set a world record for the biggest ever sale of an online item. It was a space station in online sci-fi game Entropia Universe. This month, in the same game, he's broken that record.
In a single transaction with another player, John Foma Kalun, Jacobs offloaded a mall, a stadium, a club and a "number of bio domes".
Total bill of sale for all that real estate? A cool $US335,000.
If you're wondering why people would bother with that kind of cash in a game that's not exactly the world's largest MMO, Entropia is a rare beast in that it maintains a consistent exchange rate between its virtual currency and those in the real world. That means anything and everything in Entropia has a very real and, to its players, worthwhile value.
