Did the prediction match what actually happened?

We hid Astrosphere and predicted how it would do from its 8 similar games. Every figure here, including Astrosphere's, is estimated from Steam reviews.

typical (middle half) 260k–353k
best case 1.0M (Dwarf Fortress)
Games like Astrosphere

A typical game among these

≈ 260k–353k copies

≈ $2.5M–$4.1M after Steam's cut

from ~8k 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.

Best case: Dwarf Fortress at ≈ 783k–1.3M copies, ≈ $6.5M–$17.4M after Steam's cut. It is a breakout hit, far above a typical game.

What their first month looked like
About half the games that made it here had over 6k reviews in their first month; the range was 353 to 16k.
The genre you'd be entering
These games
The similar games share Survival (7 of 8) and Base-Building (6 of 8).
The winners
Winners here lead with Dwarf + Colony Sim, priced around $30. The breakout hits carry Dwarf + Management + Strategy; a typical game here doesn't.
When they shipped
4 of the 8 similar games shipped in the last two years, so this genre is actively shipping.
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 of about 31, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
