The pain of watching your physical games become worth basically nothing

It honestly sucks watching a game you paid about 109 bucks for drop to something like 15 dollars in trade-in credit a year or so later. Half my old PS4 and Xbox One shelf might as well be coasters at this point because the value just disappears. It kind of kills the fun of collecting when you know the trade-in system barely gives you anything back, and it definitely makes me think twice before buying physical these days
