I recently started playing "Goldentowns.com" and they allow for Bitcoin > Game Gold purchases. Game Gold can also be converted to real gold bullion. But the process of trading bitcoin to game gold is a little archaic. There is not a set amount. You basically offer to buy via bitcoin, and then you have to figure out the price and how that relates to Euros, and then you get a wallet address to send coin to. Not knowing whether the seller will even accept your offer.
If you already play, let me know your price for 5 Game Gold in Bitcoin>
