Games like Solar 2

A typical game among these

≈ 969k–1.6M copies

≈ $16.6M–$23.7M after Steam's cut

from ~30k reviews

Only the top fifth of 2019's Steam releases earned $34k or more before Steam's cut, so plan for that or less.

All 8 of the similar games are hits.

These similar games lean toward the genre's biggest winners; the typical figure comes from its ordinary successes.

Best case: Stellaris at ≈ 8.2M–13.3M copies, ≈ $112.6M–$302.6M after Steam's cut. It is a breakout hit, far above a typical game.

The genre you'd be entering

These games: The similar games share Simulation (8 of 8) and Space (8 of 8).
The winners: Winners here lead with Space + Simulation, priced around $20. The breakout hits carry Open World + Building; a typical game here doesn't.
When they shipped: The similar games span 2015 to 2022, and none of them 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).
