I think its pretty clear we are headed for a mostly digital future where physical releases are increasingly treated as niche, collector items. Personally, I moved on from having physical copies of retro stuff that can be played via emulation. To me, there's no difference in having an emulation setup with roms versus having the hardware and carts/CDs. Neither setup is at risk of being disabled or taken from me, and since space is valuable, I've chosen to go with roms and emulation.

I do have about 50-60 PS3 games, another 40 or so PS4/PS5 games, and about 70 Switch games. Those are the ones I'll be keeping since they're all at risk of disappearing one day, and emulation for them isn't readily available the same way it is for everything from the prior generations. I basically buy physical whenever possible for Switch, and for PS4/PS5, I will buy the odd game here and there on disc when I know it doesn't depend on a day one download or something like that to function. I'll even track down a disc if its a game I bought digitally and realized I care a lot about it and would like to be able to play again in 20 years from now. That's kind of where my mind is at on this stuff now.
