A labeled estimate from the public review count (adjusted for release year), not exact sales. Owner data cross-checked with SteamSpy.

Does this actually work?

Only the top fifth of 2019’s Steam releases earned about $34k gross, so plan for that or less.

7 of your 8 similar games are hits.

Best case: War Thunder at ≈ 49.3M–80.1M copies. A breakout hit, far above a typical game.

The games you compared span 2012 to 2026, and 1 of your 8 shipped in the last two years.
How these numbers were worked out

A hit here: 1,000+ reviews, roughly $150k+ before Steam's cut (a standard indie benchmark).

Copies come from each game's reviews times a sales-per-review rate that falls with release age, from about 31 for the most recent game here to about 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
