Knock-knock

Short description

There is an unusual cabin deep in the woods. It had served as a laboratory and a dwelling for three generations of Lodgers.But as of late the latest Lodger has been noticing weird changes in familiar surroundings; things are missing, noises and rattle heard. Something odd is coming out of the woods.

Review count and SteamSpy's owner range disagree, so the band is widened to cover both rather than picking a favourite. Multiplied by $8.90, the average price these copies actually sold for — weighted from the price history rather than taken from the $9.99 launch price. That is 11% below list price on average. Before Steam's cut, VAT and refunds. How these numbers are calculated.

History

3 data points since Aug 1, 2026. Gaps mean nothing changed — the value carries forward.

Revenue (est.) ~$641k → ~$641k
Reviews 1,601 → 1,601
Price $2.39 → $9.99
Positive reviews 88.8% → 88.8%

The revenue curve is an estimate, not a measurement. It is the only calculated series here: each interval takes the review growth of that period, multiplies it by the sales-per-review factor and by the price actually charged at the time, and adds the result to the running total. That is why it climbs more slowly through discount periods than the review curve next to it. The last point is the same figure quoted above — gross, before Steam's cut, VAT and refunds. How these numbers are calculated.

The blurred area is the rest of the history. 256 further data points reach back to Oct 1, 2013 — your plan shows the last 90 days of it. How far each series in particular reaches is written on its own chart; not every one of them goes back that far. The shape in the blurred area is decoration, not data: the figures are not in this page at all. Plus unlocks the complete series.

Lowest recorded price: $0.99 on May 31, 2019.
