The only way to be sure is to save it on a quartz matrix. Only issue is it's read-only. Not rewritable ever. Once you etch your data into quartz that's it.
Storage is amazing, though. All of human knowledge (so far) has already been etched into such a storage medium by the UN a few years ago. It fits in the palm of your hand.
No game suggestions, friend requests, surveys, or begging.
No Let's Plays, streams, highlight reels/montages, random videos or shorts.
No off-topic posts/comments, within reason.
Use the original source, no clickbait titles, no duplicates.
(Submissions should be from the original source if possible, unless from paywalled or non-english sources.
If the title is clickbait or lacks context you may lightly edit the title.)

But I want my game library to survive the sun's expansion!
Let's play a game, of how much this would cost today.
Archive multiple copies with something that has error-correcting codes. Use btrfs, zfs, par2, rar, raid-5, DVDs etc
