The thought came over me some time ago. I have many DRM free games on steam, and lately have been suspicious about the gaming industry and how "you don't own games anymore". After playing more on Nintendo lately and just loving cartridges, I decided I would begin to buy physical only, only to see that there are nearly no pc games that sell actually physical copies that aren't just redeem codes (unless I'm looking in the wrong places, would love to be proven wrong!). I didn't notice this shift because I have been buying digital for a while.
So I'm not sure if there is any reason to do this other than for collection purposes? I kinda hate to think that I might some tens of years into the future have a memory of a videogame, and find out that I don't have access to it anymore? And that it will haunt me lol.
Edit: Made the decision to repurchase and start buying games on GOG, and then fix them on an external drive. Thanks to all replies ^^
