I should look into how to do the rollbacks, I’ve noticed it doing snapshots but haven’t needed to do that yet. Still should know before I do need it.
My worst problem so far was dual booting to Debian and having the efi entry for Garuda disappear and then not being able to get back easily without modifying debian’s grub. Not fixable with snapshots but still simple enough for me to fix.
Counter strike 2, released recently and runs on Linux, I can’t say that the people you’ll meet on that will be that great all the time, but you may be able to meet people there.
You might also be able to meet people in RuneScape or old school RuneScape, or other MMO type games, usually they have clan features where you can join a group of players.
Not sure if it’s still busy with players but kingdom of loathing also at least used to have players you could chat with live, and could join a clan or something like that in there.
