This - games used to regularly drop in price so that if you were patient as a kid you could get more for the same money, and not rush as much. I love rummage sales to this day because of finding so many great deals as a child, but still would save if needed for one in the store. First game I ever got within a week of launch was Yoshi's Island from a second hand store. Physical copies will eventually deteriorate, but they take some time to do so.... Most of my Atari and Coleco stuff still works.
