≈ $97k–$116k after Steam's cut

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

3 of your 8 similar games are hits.

Best case: Aliens: Dark Descent at ≈ 463k–753k copies, ≈ $5.1M–$13.7M after Steam's cut. A breakout hit, far above a typical game.

The genre you'd be entering
Your set
Your set clusters on Sci-fi (7 of 8) and RTS (5 of 8).
The winners
Winners here lead with Sci-fi, priced around $35. The breakout hits carry Tactical; a typical game here doesn't.
The era
The games you compared span 2008 to 2026, and 2 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).
