Not only is the Windows Store terrible; Microsoft selling core PC games as locked down encrypted "apps" is even worse.
One of the major benefits of PC gaming is that we can mod, change or improve our games to our own liking, without aid or permission of the developer or Microsoft. This is no longer true for UWP games bought from the Windows Store, and there are
plenty of other issues as well.
PC gamers who care about the perks and open nature of PC gaming really shouldn't support the Windows Store in it's current state. There are plenty of other great games to play.
One would think so. But in the past 3 years, Microsoft hasn't done anything to make their store and ecosystem (more) attractive for PC gamers. Instead, they are using exclusivity to push them into their ecosystem anyway. It seems they haven't learned anything from GFWL...
