Games like Sacred Siren

A typical game among these

≈ 3k–6k copies

≈ $9k–$14k after Steam's cut

from ~113 reviews

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

None of the 8 similar games are hits.

Best case: IKEA VR Pancake Kitchen at ≈ 13k–21k copies.

What their first month looked like

About half the games that made it here had over 39 reviews in their first month; the range was 14 to 61.

Games with under about 100 reviews in month one almost never recover.

The genre you'd be entering

These games: The similar games share Simulation (8 of 8) and VR (8 of 8).
The winners: Winners here lead with Hentai + Psychedelic.
When they shipped: The similar games span 2017 to 2024, and 1 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 43 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
