Makes me wonder why M$ won't release true Halo games on PC these days. Perhaps it would show their Xbox hardware to be the underpowered/overpriced thing it is? I suppose they need to differentiate their hardware platform form their software platform somehow.
Still, I might pick this up when it ends up in a flash sale sometime down the line.
PS: Yes, Windows 10 is pants. I really regret 'upgrading' from Windows 7. Broken 5.1 surround support, broken Bluetooth support for my DS4 controller, an extra log-in screen, spyware built-in by default... and now the Calculator app has broken! Good job, Microshaft...
