A quick tour of the different MMORPG‘s reveals millions of players spending hours and hours each day, leveling their characters, as well as earning and spending some type of virtual currency (World of Warcraft currently has over 6 million players). While World of Warcraft doesn‘t allow their players to build gold with real dollars, there is of course an "underground" market that buys and sells WoW gold. Linden Lab‘s Second Life has a virtual currency, called Linden Dollars which unlike World of Warcraft "residents" can buy, sell and earn a living from Lindens - there‘s a growing population of residents who make their living in the real world entirely from the revenue they procure in Second Life.
As the time of this writing, there are 166,922 residents, spending over 135,984.00 in 24 hours and $6.5 million USD in transactions took place is about 20 days. In 2006, there‘s a good chance $100 million USD dollars worth of transactions will flow through the virtual world of Second Life. Linden recently rolled out their own exchange, Lindex, meaning - they‘re almost a bank now.
It‘s not a matter of if, just when - credit card companies, Pay Pal, Amazon, eBay and the individual "gaming" companies eventually bridge the real and virtual currencies with loyalty programs and private label credit cards.
