I will share a collector story.
I bought my LOTR in 2004 during the FIRST run. Sold it a year later for the same amount of money I paid for the game, notably $3200.
BTW, Stern games back at that point actually had mostly complete programming code, unlike today. HUGE important point.
I even helped Stern and Keith with some of the hangups based on design and code points, as Stern regularly accepted feedback by owners and operators to make corrections. I have not seen this willingness as much today.
Played the the living tar out of the game, achieved TABA many times, but finally achieved Valinor twice, but this was AFTER the code was added!
Never looked back.
LOTR stops having "just one more game" interest unlike other games from the period such as TSPP. Playing gets labored, and you don't want to play for over an hour.
Ultimately, it's just a pinball machine, not a relic.
Another reason it sold was due to to the "grainy art" of the period times in comparison to nearly ALL other games of the previous period up to 1999, and the Wal-Mart action figures.
You just know when it's time for a game to go, and when it should stay.
This is not necessarily a long term collector title.
There is a threshold.
Some games just get eventually moved on for others to enjoy.
