MindArk's Entropia Universe is featured in the new 2008 Guinness Book of World Records for having sold the most valuable virtual items and real estate among virtual worlds. Its Club NEVERDIE, an asteroid space resort bought for $100,000 by gamer Jon NEVERDIE Jacobs, is listed as "The Most Expensive Virtual Object."

The virtual resort boasts a nightclub, shopping mall, 1000 apartment complexes, commercial space ship docking, mega sports stadium, and hunting and mining biodomes, and is said to be the highest-grossing privately owned virtual event venue online; in its press release, MindArk guesses it'd go for $1 million if it were ever placed back on the market.

The $100,000 record was almost broken this year when a virtual bank license was sold in Entropia Universe in May for $99,900 USD. MindArk estimates Entropia's daily turnover to be around $1.25 million.

"The inclusion of the space resort and Entropia Universe in the Guinness World Records book confirms the viability of our real cash economy," says Marco Behrmann, Chief Information Officer at MindArk PE AB, the development company behind Entropia Universe. "Participants realized early on the enormous potential in Entropia Universe for real commerce. In fact, the space resort had recouped its initial acquisition cost and was operating at a profit after only 8 months, and remains one of the primary event locations in the Entropia Universe."
