Peak simultaneous player numbers were also up to over three million, with over six million unique gamers accessing Steam each day. To meet all this demand, the Steam infrastructure has been increased and now has ability to run at 400Gps.
"Steam is on track to record the biggest year in its six year history," Gabe Newell, president of Valve, said in a statement. "The year has marked major development advances to the platform with the introduction of support for Mac titles, the Steam Wallet and in-game item buying support, and more. We believe the growth in accounts, sales, and player numbers is completely tied to this work and we plan to continue to develop the platform to offer more marketing, sales, and design tools for developers and publishers of games and digital entertainment."
