In the world of Azeroth, life can be cheap but saving up for that much desired epic mount can take months of labour. Welcome to the World of Warcraft, currently the world's largest MMORPG (Massively Multiplayer Online Role Playing Game). In the World of Warcraft, the auction house presents the avid window shopper with a cornucopia of wonders, from fabulous swords to armour guaranteed to make you the hardest elf in your neck of the woods. To purchase such wonders, the player needs gold, something that requires quite literally hours, days or weeks of in-game labour. However visit Ebay or Eye on MOGs, a price comparison engine for virtual commodities, and you have the opportunity to convert real life earnings into virtual gold, platinum, ISK or Credits, depending on the virtual world that you alter ego(s) inhabits.

The world of Real Money Trading has come a long way since its fledgling days when gamers departing from a virtual world would use websites like Ebay to convert their in-game assets into real world money. Today it is a multi-billion dollar industry, with industry insiders like Steve Sayler of IGE estimating that as much as $2.7 billion will change hands within this secondary market during the course of 2006. This lucrative industry is now catered for by companies like MMORPG SHOP, Mogmine and MOGS, which have entire infrastructures set up to 'farm' for in-game gold and valuable items. Not only can you purchase in-game spending power with real world money from such sites, but many are service driven, for example offering power levelling to fast-track your avatar to new heights of maturity, turn you into a master craftsman in days rather than months, or boost your reputation within the world you inhabit. Sites like Mogmine offer specialised services like fruit picking, specified item farming, or will take your character through that instance that's been weighing so heavily on your mind.

What we are experiencing here is a whole new type of economy where the border between the real and virtual world is blurring. There are currently hundreds of companies catering to this phenomenon, with some virtual items being sold for hundreds or even thousands of dollars. Virtual real estate is earning real world money, with people like 43-year-old Wonder Bread deliveryman John Dugger purchasing a virtual castle for $750, setting him back more than a week's wages. According to Edward Castronova, an economics professor at Indiana University who has performed extensive research into online economies, Norrath, the world in which EverQuest takes place, would be the 77th richest nation on the planet if it existed in real space, with players enjoying an annual income better than that of the citizens of Bulgaria or India. A visit to GameUSD indicates the current state of virtual currencies against the US dollar, demonstrating that some virtual world currencies are currently performing better than real world currencies like the Iraqi Dinar.eg, 1 US dollars equals 1500 Iraq Dinar, but you can only buy 7.5 Station Exchange service, actively facilitating Real Money Trading in Everquest 2. Other games, like the upcoming Roma Victor, embed the secondary market as part of their financial model rather than relying on the common subscription model, with players purchasing Sesterces to play and advance in the game.

Such trading of virtual goods for real world money is potentially just the tip of the iceberg for the development of virtual economies where people come together within virtual worlds to promote and trade real world products. Games like The Matrix Online already sell advertising space to real world companies to promote their products to gamers who spend their leisure time within the world.

We are thus embarking on an entirely new type of economic activity, where real and virtual worlds are meeting within an economic sphere. As a fledgling economy, it is difficult to chart where this phenomenon may take us, but the sheer weight of currency being spent and earned within these economies and the development of services to monitor real to virtual exchange rates and market prices indicates that they are here to stay.
