So, just a bit of "investigating" on the GFWL logo thing, based on the sites, so don't expect anything too conclusive.
This is Dark Souls 1. Not much to it, GFWL widely announced, making people all over the world miserable. Links to:
http://www.xbox.com/en-US/live/pc
Dark Souls 2 uses a generic PC logo that links to the same site as the GFWL logo in Dark Souls' 1 site. Still, it's weird that they didn't use the same logo that they clearly knew that existed a couple months ago.
Hitman Absolution isn't GFWL and uses the better known PC DVD-ROM logo that links to nowhere. I checked about a dozen other non GFWL titles and they all had this logo.
Arkham City doesn't give a shit and doesn't say GFWL, even though its venom is pouring through its veins. I looked at some of other GFWL games sites, like Iron Brigade and Dead Rising 2, and the logo was nowhere to be found, while others like Bioshock 2 and Fallout 3 sported it with pride.

So basically I just wasted 20 minutes
