Every market we collect.

Reviews, worldwide (the counter carries no country): 2739.8/day in the week to Jul 16 → 6.14/day in the week after.

For scale, across Steam · Top Sellers · Poland over the last 30 days: the 20 chart moves that followed a price cut of more than 20% went a median of 10.5 places towards #1, and the 2,491 moves with no price cut behind them went 1 away. 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.
