Virtual Goods

Because i have been looking into 'Micro-transactions' as a main topic i forgot that 'virtual goods' is a large part of the transfer. Players are spending millions yearly on virtual goods by why and how much virtual goods are being sold?

I have come across a website called Virtual Economy Research Network which discusses the nature and potential in Virtual Goods. Although the artical was written back in 2007 it has some interesting information that allows us to help maybe see the change in virtual sales. According to them as an estimate $2,090 million is what the worldly spenditure on virtual items will be at the end of 2007.
