The ony thing GFWL means is that sooner or later you are going to have to pay for online PC gaming. Keep the PC platform more open and don't give way to GFWL. DRM and things like GFWL cocks everything up for anyone who wants to play when not connected or do a litte moding... or a lot. The only thing that can save PC gaming is keeping it PC gaming. Consolization is not the way to go. Looking at you L4D and COD: MW2... amongst others.
Proper PC gaming is far superior to console gaming.
