Does delisting happen that often? I think it's not a huge issue. Games on discs are a thing of the past. It's a bit like how I got used to keeping my music as MP3 files. It takes a bit of time to get used to. But for me, I'm ready for an all digital future.

If the game was still complete on a disc, you'd have a point. But these days you pop in the disc and get a rather big update file of 20 tot sometimes even 100GB. We have to start accepting that our games just aren't on discs anymore.

One day you will download complete libraries of PS4, PS5 games and so on in seconds like you would with NES and SNES. And there will be way better stuff out there. Old things won't be lost :) Heck even all PS1 games ever released I can emulate on a cheap tablet with enhanced sharper visuals. Enjoy the moment, and look to the future!
