Notes on the data, the site, and what changed this week.
Sold listing screenshots are in
A guide price is only worth as much as the comps underneath it, so the
comps are now something you can look at. Click a listing title on any
game’s sold listings table and the capture of that listing opens over
the page — the title, the photos, the price and the date, as the
listing looked when it sold.
Older listings were recorded before captures were kept, so a few will
say the screenshot has not been added yet. Everything imported from
here on has one.
Why a median, and not an average
A guide price here is the median of the last 90 days of
sold listings for that condition, down to a single comp — the
card says how many it rests on. That is a deliberately boring rule, and
it is the same rule for a $12 Wii U platformer and a sealed launch
title.
Averages lose to a single bad comp. One mispriced auction, one lot of
five games sold under one title, one listing where the seller ate the
shipping — any of those drags a mean somewhere the market never
went. A median just steps over it.
The same applies to the price history chart: each point is that month’s
median, not that month’s high sale. It is why the lines look duller than
the listings feel, and that is the point.
What this site is
Nintendo pricing, from sold listings only: Wii U, Switch and Switch 2,
with the special editions and regional variants kept as their own
entries rather than folded into the base game.
There is no asking-price data here on purpose. What a copy is listed at
says what a seller hopes for; what a copy sold for says what somebody
paid. Only the second one is a price.
Sign in and you can track what you own, what you paid for it, and what
the guide says it is worth now.
