Yeah it pretty much depends on print run. If it's a smaller company, then the value will actually get higher such as Atlus, though they're going digital which will help that problem.

I'm usually more amazed when a game price stays consistently high when you feel like it shouldn't. Such as mainline Nintendo games, those games rarely drop in value and when they do, you might as well hunt up a new copy since the price difference is slim. I remember how Mario Galaxy, Skyward Sword, and Brawl almost never decreased in value on the Wii.
