History
3 data points since Aug 1, 2026. Gaps mean nothing changed — the value carries forward.
The blurred area is the rest of the history. 191 further data points reach back to Oct 1, 2010 — 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 price in the visible window: $0.00 on Aug 19, 2026. That is the current price.

Studio counts the titles that developer has released — the closest thing to production scale that public data allows. It is not a budget, and nobody publishes those.
