I know nobody will care, and some of those who don't might still insult me for saying this, but...
As long as you rename MGI_Data\Plugins\AudioPluginDearVR.dll to something else (with a suffix different from .dll) or just delete it, this game even works on Windows XP Pro x64 Edition (without VR, obviously). Quite amazing, considering that its system requirements are "Windows 10" in regard to the OS, at least on Steam.
But hey, it's compiled for NT 5.2 64-bit (XP x64, Server 2003 x64), so the platform toolset is likely v140_xp or v141_xp, and it even offers a Direct3D 9.0c renderer (although... Why not go with OpenGL? Version 4.5 is available on XP x64 with the last nVidia drivers, and it can do much more than D3D9 can).
But anyway, I'm quite surprised. Your platform compatibility is pretty amazing, even if you might not even know it yourself. ;)
Also, I welcome your choice to exclude DRM. I could download this game on Steam on Windows 10 x64, then copy it over to XP x64 and just play it there after renaming said DLL. No SteamStub DRM, no Steam API DRM. Awesome!
So, just for that, I'll definitely buy the full version once available (or maybe even an earlier instance).
Thanks! :)
PS.: How/where can I send you a crash dump? If you're interested, I can send you one with the stock version of the game, so with MGI_Data\Plugins\AudioPluginDearVR.dll still in place.
