I know this is a pretty common question, but the Google results don’t seem to offer a good solution and are mostly aimed at people who already know Linux.
I am looking to switch from Windows, where I have my OS and whatever big game I’m currently playing on my 128GB SSD, and everything else (games, most software, documents, ect.) on my 2TB HDD. ELI5, How would I replicate this on Linux? I’m planning on installing Mint, but am open to using Bazzite if it offers any additional tools for this sort of this.


You can use something like Lutris and have a different Wine directory for each installed game. These can be placed anywhere on your filesystem that you like.
I’m less familiar with GOG. I do know there are a few different launchers that try to solve this and other problems for managing Windows games.
Heroic Games Launcher or Bottles for GoG and Epic games.
