Games like Friendly Fire

A typical game among these

≈ 88k–445k copies

≈ $546k–$2.0M after Steam's cut

from ~3k 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: Brothers - A Tale of Two Sons at ≈ 2.6M–4.2M copies, ≈ $10.8M–$28.9M 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 Platformer (6 of 8) and 3D Platformer (3 of 8).
The winners: Winners here lead with Story Rich + Emotional, priced around $15. The breakout hits carry Atmospheric + Story Rich + Controller; a typical game here doesn't.
When they shipped: The similar games span 2013 to 2021, and none of them 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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
