Valve announced a change for Steam today that will make things a lot clearer for everyone, as developers will now need to clearly list the kernel-level anti-cheat used on Steam store pages.
Now if only they could more clearly communicate when games are playable offline.
I bought Sea of Thieves about 5 years ago. Recently, they added kernal-level anticheat (which does precisely fuck-all to actually stop cheating). While that is annoying, I'm not particularly worried because the studio that makes that game is owned by Microsoft, and like all Microsoft products, it was banished to my windows partition with the rest of the spyware.
Only if those other partitions are not encrypted. Sure, it could still wipe them - but that's something that backups are good for, and something you would certainly notice immediately :)
