Also, I agree with Hexen. I await the day the market crashes. Vintage gaming will never die, but a big price drop is bound to happen. It's only the calm before the storm.
Any reasoning behind this theory? I'm not saying I disagree, but I was just curious why this would come about?
It's been discussed earlier in the thread, but here's my theory. Here's a little timeline using NES as an example. I have a good friend who runs the game trading part of a popular local comic shop, and we've discussed this many times over the past years, and some of our theorycrafting has come to light. Even though it's a theory, it's an informed one.
Production, 1985-1995: NES games are available at Zellers, Woolworths, Macy's, etc. Super Mario Bros. 3 cost around $45 new.
Obsolescence, 1995-2006: Newer consoles are released. The NES becomes obsolete. The majority of NES games become available for dirt cheap on the free market. It was common to see Super Mario Bros. 3 and Legend of Zelda carts in pawn shops and grottos for ~$5 in the early 2000's.
Trends, 2006-Now: Demand slowly goes up because of recent trends (8-bit aesthetic, AVGN, Let's Players, etc). It has yet to peak. but signs of slowing within the few years are possible, but that will be discussed later.
Hoarding, 2008-2009: Soon-to-be resellers buy all the stock at these unassuming stores. NintendoAge is the epicenter for these resellers.
Market Spike 2010-Now: Resellers take advantage and spike the market. Unassuming hipsters keep purcahsing at ridiculous prices. Small stores catch on. Super Mario Bros. 3 is $30 at my local video store.
There are two ways the economy can die after this.
Redistribution of Wealth: The demand goes down because it's just a trend for most people, then the prices will in turn go down as well, as resellers perform damage control on a dying market and liquidate their stock. This is where we come in and roll around in games like Scrooge McDuck (metaphorically of course, but we would have that many games after this happens.)
Back to the Future Part 2 Theory: (Worst case scenario! Grab your light guns, stand your ground, and vote R.O.B.ublican) Though that copy of Jaws in the window might not cost $100 in 2015, it might in 2020. The demand skyrockets (Let's Plays and the like still being popular for years to come), supply will go down, in time prices will go way too far up, and the demand will slowly die as no one will buy a copy of SMB3 for $80. It'll be hard for new collectors to enter the game, and old collectors will already have the games that are expensively priced.
However, it could always stay the same. It's unlikely because of how the market fluctuates, and with trends still being popular as ever, or more so, but it always
could become a mobius strip of prices falling and rising, never going anywhere. Fear the future.
EDIT: burningdoom, you hit the nail on the head. Can't believe I forgot to make the comic comparison.
