I migrated to linux when Windows 7 died. So I’m you from years ago, lol.
If you’d like any advice, I would just say check ProtonDB for the games you regularly play (especially if they are MMOs) to make sure they work, cause anything that uses restrictive kernal level anticheats arent going to run.
and if you are looking for a distro, I would personally recommend Nobara. it stays up to date, it has a lot of the gaming stuff built in (Some of which might require compiling from github otherwise), and its been rock solid for me personally. but you should poke around and find whatever tickles your fancy… and anything you don’t get from X, that you can get from Y, can usually be manually installed on Z.
