Few details were revealed of the server-side, "zero-day" anti-piracy solution. However, Microsoft did note that Games for Windows Live will now require authentication for online play.
In-game marketplace capability has also been added, allowing developers to sell content through their own store fronts through customized APIs. Games for Windows Live will now save users' settings in the cloud, allowing access to the settings regardless of the PC used.
"This update and other features currently in development represent a tipping point in the evolution of Games for Windows Live as a leading online PC gaming network," said general manager of Games for Windows Live Ron Pessner. "In the coming months, we will continue to deliver on our promise to provide gamers and publishers with the industry's best connected gaming experiences through the Live service."
We'll have more details on the updates following a briefing with Microsoft later today.
