Games like Seashell

A typical game among these

≈ 11k–13k copies

≈ $46k–$85k after Steam's cut

from ~349 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: Penko Park at ≈ 17k–27k copies, ≈ $64k–$173k after Steam's cut.

What their first month looked like

About half the games that made it here had over 61 reviews in their first month; the range was 7 to 155.

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

The genre you'd be entering

These games: The similar games share Collectathon (8 of 8) and Nature (7 of 8).
The winners: Winners here lead with Creature Collector + Collectathon, priced around $14.
When they shipped: The similar games span 2019 to 2025, and 3 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 36 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
