fake news
srsly though, I believe Microsoft is working on a solution to solve Steam/Windows 10 Store connectivity too, so hopefully the communities won't be split up (but still working on getting that bit of info confirmed).
I've been saying from the off that Microsoft will eventually let the other shoe
mostly drop and release its WinStore games on Steam with Uplayesque Xbox App integration, minus the Play Anywhere perk (the WinStore does need to have a feather in its cap, after all). Halo Wars 2 seems like a good a starting point as any.
If nothing else, Microsoft has to realise that Quantum Break and now Halo Wars: DE have set a precedent. Many people waved away the Steam release of the former as a contractual wrinkle owing to the fact that Remedy is a third-party development partner, but the same can't be said of the latter and 343i.
Some wheels are definitely turning. What path that cart is taking remains to be seen, however I'm fairly confident that Microsoft has finally realised that attempting to force people to use something they'd rather avoid is largely ineffective. I mean, an Xbox gamer taking advantage of their complimentary WinStore copy doesn't actually help the service gain traction within the PC DD space, and that's chiefly who the WinStore appeals to -- people who are
already members of the ecosystem, not those entrenched elsewhere.
To be perfectly honest, I'm of the opinion that GFWL was Microsoft's one and only shot at crippling Steam and it screwed the pooch
utterly. Today's WinStore push is too little -- it's literally still fundamentally flawed as a content delivery service -- too late. If you'll excuse the flowery prose, Microsoft is pushing a rock nobody who primarily games on the PC actually wants up a hill that Valve has been comfortably sitting atop of for years, and for good reason: Steam continually improves whereas the WinStore is still as unreliable as it was when Rise of the Tomb Raider launched
well over a year ago.
