Games like ISLANDERS

A typical game among these

≈ 895k–1.4M copies

≈ $5.2M–$13.8M after Steam's cut

from ~30k 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: Planet Zoo at ≈ 2.8M–4.6M copies, ≈ $34.9M–$93.8M 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 16k reviews in their first month; the range was 6k to 34k.

The genre you'd be entering

These games: The similar games share Sandbox (7 of 8) and Simulation (7 of 8).
The winners: Winners here lead with Simulation + Building, priced around $45. The breakout hits carry Economy + Building + Management; a typical game here doesn't.
When they shipped: The similar games span 2014 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 70 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
