Portal 2 on PS3 is a landmark moment for Valve, showing not just their commitment to the platform, but also linking PSN and Steamworks. Portal 2 on PS3 comes with a copy of the game for Steam, and it might not be the last game with such a collaboration.

“The goal is to give a Portal 2 customer access to their game on as many devices as possible. We introduced this notion when we launched Steam Play for Mac and PC games in the spring of last year,” said Doug Lombardi, Valve’s VP of Marketing. “Giving a PS3 owner of Portal 2 the ability to also play their game on the PC and Mac is an extension of this philosophy. From our perspective, it’s not two copies of a game; it’s the same game, but with Sony’s help we’ve worked out a method to allow that Portal 2 PS3 customer to also play their game on the PC and Mac.”

“We are hoping other titles will benefit from the Steamworks tools and services we’ve created for Portal 2 PS3, but we don’t have anything to announce today,” he added.
