Did the prediction match what actually happened?

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

Copies, estimated from reviews

typical (middle half) 1.0M–1.1M

best case 9.9M (RimWorld)

Games like Breachway

A typical game among these

≈ 1.0M–1.1M copies

≈ $12.4M–$19.7M after Steam's cut

from ~29k 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: RimWorld at ≈ 7.6M–12.3M copies, ≈ $72.7M–$195.4M 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 20k reviews in their first month; the range was 11k to 26k.

The genre you'd be entering

These games: The similar games share Simulation (6 of 8) and Building (5 of 8).
The winners: Winners here lead with Building, priced around $22. The breakout hits carry Base-Building + Building + Colony Sim; a typical game here doesn't.
When they shipped: None of the similar games shipped in the last two years; the newest is from 2021. That says more about which games were found than about the market.

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 43 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
