This is true for me... Windows for gaming.

There are a few other things I need it for (like FPGA/circuit tools, home theater programming, etc.) but those can be easily handled by a VM.

That said, I am thinking of switching back from Mac to Windows for a daily driver, or to Linux, because these new MBPs are so bad. I need another keyboard replacement and I do not want to be without my computer for a week. This time double keypresses instead of none. What a joke, and the TouchBar makes VI hard (and no, after 31 years of VI I am not switching to caps lock).

i run win steam with wine and the games work surprisingly well most of the time

Steam for Linux now runs some games under their own Wine btw there's a good number of them they support now.

Yes, for anyine who wants to do further research it's called Proton. Valve has tried several times in the past to make gaming on Linux more attractive, but this has by far been their most successful attempt.

A lot of games don't even start on my Antergos setup. I refuse to run ubuntu, because I don't like it (mostly package naming, and a lot of the time I feel like it's poorly configured at least when I was starting out). I personally have had a negative experience whenever I use a Debian derivative.

I was able to install Steam on openSUSE if you don't mind openSUSE, it's a good alternative option.
