With a rise in popularity and a debut on impending, Valve's platform looks to evolve further with micro-transactions.

According to a report by BigDownload, is releasing new tools that support micro-transactions. In short, the ability to sell content from within games at low prices such as 59p/99c.

The concept of micro-transactions isn't a new one - it drives the gaming market in China, for example - but its introduction to Steam would be a big step toward adoption in the and Europe.

While micro-transactions are now supported in Steam, no developer has announced plans to utilise the feature. Expect someone to step forward and tinker with them soon, though.
