Very pleased if other MS published titles made by third party studios follow suit. Especially Scalebound. Kind of strange that there's still no word on Sunset Overdrive getting any kind of PC release.
As others have said, I doub this will happen wi Halo/Gears/Forza, but you never know.
Just because MS own the IP doesn't mean there wasn't a deal originally agreed to let Remedy do this. I assume Remedy are self publishing on Steam, but it would be interesting if not.
MS still never released any UWP game sales figures, right?
I gather that one of the few positives with the Windows App Store is that they are pretty lenient with refunds. I wonder how they would respond to anyone requesting a refund because they never thought it would be on Steam, and want to buy it there now instead.
