Games like I Am Alive

A typical game among these

≈ 1.9M–3.8M copies

≈ $28.7M–$55.5M after Steam's cut

from ~80k 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 7 of the similar games are hits.

Best case: Fallout 4 at ≈ 21.0M–34.1M copies, ≈ $115.2M–$309.7M after Steam's cut. It is a breakout hit, far above a typical game.

These games
The similar games share Post-apocalyptic (7 of 7) and Open World (5 of 7).
The winners
Winners here lead with Open World + Post-apocalyptic, priced around $20. The breakout hits carry Exploration + RPG + Adventure; a typical game here doesn't.
When they shipped
The similar games span 2015 to 2025, and 2 of the 7 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 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
