≈ $100–$2k after Steam's cut

from ~12 reviews

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

2 of your 8 similar games are hits.

Best case: Kerbal Space Program at ≈ 7.1M–11.6M copies, ≈ $78.6M–$211.3M after Steam's cut. A breakout hit, far above a typical game.

What it took to get here

The games that made it here had under 31 reviews in their first month.

Under about 100 in month one, almost nothing recovers.

The genre you'd be entering

Your set: Your set clusters on Space (5 of 8) and 2D Fighter (3 of 8).
The winners: Winners here lead with Space + Simulation, priced around $30. The breakout hits carry Simulation + Building + Sandbox; a typical game here doesn't.
The era: The games you compared span 2015 to 2024, 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 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
