Did the prediction match what actually happened?

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

Copies, estimated from reviews

typical (middle half) 4.4M–6.0M

best case 23.0M (No Man's Sky)

Games like Exo One

A typical game among these

≈ 4.4M–6.0M copies

≈ $36.5M–$50.0M after Steam's cut

from ~123k 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: No Man's Sky at ≈ 17.5M–28.5M copies, ≈ $289.3M–$777.8M 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 40k reviews in their first month; the range was 5k to 93k.

The genre you'd be entering

These games: The similar games share Exploration (7 of 8) and Space (6 of 8).
The winners: Winners here lead with Exploration, priced around $50. The breakout hits carry Sci-fi; a typical game here doesn't.
When they shipped: The similar games span 2016 to 2023, 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 52 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
