This has probably been brought up before but... when a buyer of a game wants to find out its current value, many times they go to pinside and get a number from the "average value".
Unfortunately, that average value number includes games sales from 5+ years ago... back when you could buy a TZ or a TAF for $4k. Pinside is using game sale prices from 5+ years ago to formulate a current value. That's crazy and a disservice to buyers and sellers.
We all know pinflation is out of control lately and good working DMD pinball games are pretty hard to find for sale locally... for any amount.
When someone lists a game for sale... say, a waterworld for a reasonable $2600 - $2800, a buyer sees pinsides average value from $1800-$2150 and thinks the $2800 price is way too much.
Is there a better algorithm that pinside could use to give a more realistic valuation of pinball games now and going forward? I'd suggest maybe only using sales within the last 12 months?
