Steam has been growing pretty quickly this year and they've announced that there are now well over 30 million users enjoying the service.
In the last 12 months, Steam's user base has grown 178 per cent. There are currently at most over three million users on Steam at any one time with six million unique users on everyday.
"Steam is on track to record the biggest year in its six year history."
Valve's Gab Newell points out that this huge growth is in part thanks to the launch of Steam on Mac as well as the introduction of the Steam wallet.
