Only the top fifth of 2019's Steam releases earned $34k or more before Steam's cut, so plan for that or less.

6 of the 8 similar games are hits.

These similar games lean toward the genre's biggest winners; the typical figure comes from its ordinary successes.

The winners: Winners here lead with Open World + Flight, priced around $25.
When they shipped: The similar games span 2017 to 2025, and 2 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).
