Linux

By now all the games are supported pretty good on Linux

I don't mean to hijack the thread, but I don't want to start a new one for a related question. I understand I will probably have to wipe or partition my primary drive, but will I be able to use my other drives as-is, and have access to all of my files and things?

I have been able to play most games fine on Linux mint.

If he plays Minecraft bedrock he can use “Minecraft bedrock launcher” which loads the android version (if you own it on the play store). Minecraft Java works find on Linux, but I prefer bedrock to use a controller.

Some PC games I play in “bottles” which lets you run windows programs.

I also have “heroic games launcher” that lets me play epic games, gog games and Amazon games.

I recommend the Xubuntu flavor of Ubuntu.

Others have already advised you on how to run Windows games, but in my experience with these games:

The Sims

I've been playing it just fine on Wine, check EA App on AppDB

Cities Skylines

The first game has a native Linux version, not sure how the second game runs on Proton

Stardew Valley

Native Linux

Minecraft

It's Java so cross-platform, including Linux

Generally you can check ProtonDB for Steam games, and AppDB for others.
