I play modern games on Linux all the time, using Steam, but there are also other ways. Firefox/Chrome supports DRM (ugh) for Netflix etc.
You may need to install graphics drivers manually though, to get the proper drivers for your GPU. Otherwise, most works but need some more initial tweaking than on Windows, but then much less, more stable, secure and private.
That's good, things have improved over time. Stability-wise, I've had zero problems with W10, it has been completely solid.
