Quoted from Daditude:
I attribute it to the price going up a lot on this title as people are discovering its value through spending more time playing it in the pandemic. There are just a few titles that have outperformed others significantly. This is one of them.
The value has skyrocketed as well. When I first got into the hobby you could find a players shadow for less than $2k and it was not that long ago you could get one for $2500. Now they are pushing white water money.
