≈ $644–$10k after Steam's cut

from ~23 reviews

Only the top fifth of 2019’s Steam releases earned about $34k gross, so plan for that or less.

2 of your 8 similar games are hits.

Best case: Gone Home at ≈ 1.2M–1.9M copies, ≈ $4.8M–$12.9M after Steam's cut. A breakout hit, far above a typical game.

What it took to get here

About half the games that made it here had over 6 reviews in their first month; the spread ran 3 to 60.

Under about 100 in month one, almost nothing recovers.

The genre you'd be entering

Your set: Your set clusters on Exploration (8 of 8) and Walking Simulator (8 of 8).
The winners: Winners here lead with Walking Simulator + Story Rich, priced around $17. The breakout hits carry Story Rich + First-Person + Atmospheric; a typical game here doesn't.
The era: The games you compared span 2013 to 2025, and 3 of your 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).
