I definitely only care about a handful. I've got categories like "beaten", "in-progress", "maybe someday", and "meh". You accumulate a lot of free stuff over the years, things you got because they were in a cheap bundle with what you wanted, the thing you bought to play with a friend and did exactly once, etc.

GOG's similar. I've got so many things that I bought for $0.80, got for free, or bought for the memories and haven't actually picked up.

That's just on PC. I have a lot of physical media for a lot of different game systems. I think I'd probably have enough games on hand for the rest of my life if Steam and GOG both disappeared tomorrow.

thats why i usw gog and download the backup files to ma chunk drive. If Steam decides to block the game, even if you have the backup files, it might not start because auf the steam integration. It never happened to me, but as a possible scenario. I also use cachyos with heroic loader, at least my epic games are safe, as when they are sideloaded, i backup the wine/game folders from time to time (only the games i liked), and my epic library is so huge, because of the free games, i cant play all of them anyway. Also thr steam/humblebundle shit yes omg.. i have over 2500 games not played, not counting my emustation library (where i have all top 100 games for pretty much all famous consoles gb,gbc, n64, saturn, wii, psx, ps2,.. and a a few more)

The plan is make hoarding data(including games) your hobby. There is no need to wait until your imaginary game archive is inaccessible; start buying hard drives now. With modern day ZFS/NAS technology there's no reason not to have at least a couple terabytes to backup your favorite games.
