Did the prediction match what actually happened?

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

Copies, estimated from reviews

typical (middle half) 3.0M–10.8M

best case 105.1M (Garry's Mod)

Games like Modbox

A typical game among these

≈ 3.0M–10.8M copies

≈ $21.7M–$96.2M 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.

Best case: Garry's Mod at ≈ 80.0M–130.1M copies, ≈ $219.9M–$591.3M 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 49k reviews in their first month; the range was 31k to 122k.

The genre you'd be entering

These games: The similar games share Sandbox (8 of 8) and Physics (7 of 8).
The winners: Winners here lead with Sandbox + Moddable, priced around $10. The breakout hits carry First-Person + Multiplayer + Casual; a typical game here doesn't.
When they shipped: The similar games span 2006 to 2026, and 2 of the 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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
