Comment by foresto

Pick a popular distro, and during installation, put your /home directory on its own partition. This way, you won't have much to reconfigure if you ever have a reason to switch distros. (You might not ever have a reason; they're all pretty capable.)

If using Ubuntu LTS for gaming, you might want to add a newer kernel: https://ubuntu.com/kernel/lifecycle

Linux Mint would also be a reasonable pick.
