Basically, the GFWL Marketplace is saying bye-bye, and that means the games on PC that are directly tied to GFWL will not be purchasable through it any more. That’s a bit lame if those games aren’t available anywhere else on PC, of course.
Luckily, Michel Gagné’s Insanely Twisted Shadow Planet (ITSP) is available on Steam, but even when you purchase the game through Steam, you have to go through GFWL sign-ins and all that nonsense to play it. However, I asked Michel if GFWL being shut down would affect the game at all. And he replied with the rather marvellous:
“ITSP will continue to be available on Steam. In fact, soon it will be GFWL-free. Thank God!”
Being published through Microsoft on the Xbox 360 meant that the same happened to ITSP on PC, and that came with GFWL requirements, even on Steam. But now, with GFWL going the way of the dodo, it will lose all connections to it, so at some point, when you either purchase or open up ITSP, it will be without all of those annoying and unnecessary steps tied to it.
The removal of GFWL from the game may seem like a small thing in the grand scheme of things, but it was like one of those tiny flies that won’t stop buzzing around your ears. With it gone, everyone’s happier.
