Windows 10 store exclusive means it is built as a windows app which means:
* No SLI/Crossfire,
* Windows 10 store download is buggy,
* No refund policy explained,
* Vsync is always on,
* Always borderless fullscreen,
* Game files are protected,
* Can't launch it via the exe (So adding it as a non steam game will not work)
* No fps/hardware monitor software works with it,
* You need to take control of the folder as admin if you want access to the files
* Mouse software which lets you create custom binds for each game doesn't work
* Say bye to using sweetfx and mods
