Games like Unturned

A typical game among these

≈ 5.9M–9.9M copies

≈ $72.0M–$93.6M after Steam's cut

from ~202k 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: Wallpaper Engine at ≈ 31.0M–50.3M copies, ≈ $42.5M–$114.3M after Steam's cut. It is a breakout hit, far above a typical game.

The genre you'd be entering

These games: The similar games share FPS (6 of 8) and Open World (4 of 8).
The winners: Winners here lead with Mature + Utilities, priced around $5. The breakout hits carry Mature + Utilities + Anime; a typical game here doesn't.
When they shipped: The similar games span 2016 to 2025, 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 52 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
