Charts
Each storefront's own chart, in its own country — the closest public signal to sales where none is published. A country missing from a list is one we don't collect there, not one where the game doesn't chart.

Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.86/day in the week to Aug 26 → 0.57/day in the week after.
One market had a chart position on both sides of this cut. One sale in one country is an anecdote — read it next to the store-wide figures below.
For scale, across GOG · Trending · United States over the last 30 days: the 103 chart moves that followed a price cut of more than 20% went a median of 47 places towards #1, and the 6,574 moves with no price cut behind them went nowhere. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
