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.
