It's obviously a bubble over the past year or so. Prices are 2-4 times what they were early last year. I don't know what caused the sudden sharp increase in market value, but it has reached the point where it is harming my gaming. I only buy what I want to play. I don't buy to speculate, to hoard, or just to have a game sit on my shelf. I just want to enjoy the games on my CRT TV with the original hardware.
I hate to think how many copies of Harvest Moon SNES are just sitting around in closets or on shelves, unplayed, while I am trying to find a copy on Ebay for a price that doesn't equal four other good games.
