Games like Devil's Island

A typical game among these

≈ 438k–1.2M copies

≈ $4.1M–$12.8M after Steam's cut

from ~16k 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: Metro Exodus at ≈ 3.4M–5.5M copies, ≈ $27.9M–$74.9M 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 8k reviews in their first month; the range was 254 to 14k.

The genre you'd be entering

These games: The similar games share Survival (7 of 8) and Post-apocalyptic (5 of 8).
The winners: Winners here lead with Post-apocalyptic + FPS, priced around $30. The breakout hits carry Singleplayer + Story Rich + Action; a typical game here doesn't.
When they shipped: The similar games span 2017 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 43 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
