You can recoup 3/4ths of the cost of buying a used game on ebay by re-selling on ebay yourself after you are done with it, or half of the cost by selling that game to Gamestop, or a quarter of the cost by buying new from Gamestop and then selling back to them when done.I moved from physical in 2018... I don't see why anyone would buy them outside of special/collectors editions. putting a disk in to play a game.... sorry bro but you are trapped in the 90s/00s
I mean, I am a collector and don't do that, but none the less, its an option.
edit: And speaking of which, without used games to compete with, a lot of publishers will stop dropping prices. Obviously some (*cough*Ubisoft*cough*) live quarter to quarter and will still drop theirs but no physical would make Nintendo even more likely to keep everything at launch price, and they're far from the only ones, Square hate dropping prices too, Bandai seems to keep theirs high and I am sure I could find more if I actually bothered to look.
