Hi
@shipthepilot - make Google your friend
I am not a Gamer, but I have taken your last 6 words "run windows steam games on Linux" and applied them to Google.
Look for most recent articles, or ones that say "solved".
One I found that looks promising is
https://askubuntu.com/questions/777115/running-windows-steam-on-linux-using-wine/777120
WINE stands for "Wine Is Not an Emulator", and can be used for playing Windows games and running programs. It can be hit and miss.
You could tell us your Linux Distro down to the version and DE (Desktop Environment), for example Ubuntu 18.04 MATE, Linux Mint 18.3 Cinnamon.
I would be looking to install Timeshift first, take a screenshot, and then if things go wrong, you can roll back your system.
I have a Tutorial
here that tells about Timeshift (it is like Windows Restore but better) and ways to install it.
If you are using Linux Mint 18.3 or higher, or Linux Lite 4.0 or Manjaro Strit, then Timeshift is already installed.
Cheers and good luck with the Games.
