Quoted from 27dnast:
This reminds me of what happened to baseball cards back in the 80s. Baseball cards got uber popular - truly rare (old cards that survived attics and shoe boxes) cards got super expensive and new young player cards from newish standard run of the mill yearly releases were gaining value. Think of those newer players as the Trons and IMs (pre Vault Edition) of the pinball world.
This analogy still doesn't apply. A baseball card is an object you look at and hide away. Its entire value is that someone else might want it.
A pinball machine on the other hand, is a game. Sure, I collect them, but I play them. And Tron is a perfect example. I bought mine NIB, and it lost some value the moment I opened it. Later it was worth more, then less, and then more again. And none of that mattered because I think it's a very fun game. Right now, I could sell it and make a nice profit, but I wouldn't have Tron to play.
In the end, the "value" of my. Tron could drop to $2000, and I wouldn't care. It would still have the value of fun. This is the difference between this and cards. When MMr was announced, I almost jumped on it, but even though it was a big drop in price, I never considered MM to be 8k worth of fun, so I passed.
