Notable to the list of titles that won't work is Destiny 2.
Having said that, I've been using Linux as my daily driver for everything, including gaming, since June, and I haven't run into many issues. It's certainly worth the minor hassle entailed to get some titles to work, if only to get away from Windows 100%. You can always dual boot.
If you aren't very technical, I would also consider Linux Mint. You won't always have access to the latest and greatest, but it's simple and very easy to learn if you're coming from Windows.
I do love polybar, though.
