Entropia Universe AB, the largest MMORCE around (that's Massively Multiplayer Online Real Cash Economy game)this week invited billionaire businessman Warren Buffett to try his financially astute hand at the game.
EU invited Buffett to buy up some Calypso Land Deeds (which went public back in 2011 at $100 and have appreciated to $140 over the last three years) noting that these yielded a better return than his own Buffett's own company, Berkshire Hathaway. It also noted that as rich as Buffett is, he still doesn't own a single space ship.
