I haven’t used it myself, but I hear Bazzite provides an experience similar to SteamOS. Note that some competitive online games with kernel-level anti-cheat won’t work on Linux. Most other games should run fine, though.

Imma let you finish, but BeOS is the best microkernel operating system of all time! OF ALL TIME!!!

I just know how to use search engines and follow instructions written by people smarter than me.

99% of being a programmer is knowing what to Google, so you’re halfway there.
