If Microsoft were to revive GFWL. How would they market and and build it to be able to better complete with other similar services such as Steam, Origin and Uplay.

Let's us be the board members for this and see how best a service like GFWL could come back from the ashes. They may already be planning to do this with the arrival of Windows 10 and they did say that they were looking to get more into the PC Market more.

Hell I'd be happy if they ported over the Halo Franchise especially including Halo 3, ODST and Halo Wars over to the PC with good optimised ports and hopeful (unlikely) mod support.

How do you guys think they could pull it off realistically?
