I argue that digital is good as long as you make backups of your games.
I have an external drive full of steam games that steam can’t touch. So I’ll always have those games. Barring I lose the drive or don’t transfer the files before it becomes unreadable.
Another example where digital is good imo is the Switch. Those tiny game cards can suck my ass. If I drop one on my carpet it’ll be gone until next spring. Having multiple games saved on SD cards is the way to go.
Other than that, I agree.
You’re backups wont work if valve ceases to exist, since you need to be logged into a steam account, that owns the games, to restore the backups.
Same reason my D2D games ceased to work, cause D2D went away, along with their authentication servers.
That hasn’t been true for like ten years now.
Obviously anything that needs an internet connection will require steam. But pretty much almost all single player games do not need steam to run.
