A typical game among these

≈ 13k–43k copies

≈ $25k–$167k after Steam's cut

from ~681 reviews

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

4 of the 8 similar games are hits.

Best case: Antichamber at ≈ 1.1M–1.8M copies, ≈ $6.2M–$16.6M 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 215 reviews in their first month; the range was 69 to 680.

The genre you'd be entering

These games: The similar games share Puzzle (8 of 8) and Exploration (7 of 8).
The winners: Winners here lead with Puzzle + First-Person, priced around $20. The breakout hits carry First-Person + Surreal + Singleplayer; a typical game here doesn't.
When they shipped: The similar games span 2013 to 2025, 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).
