A typical game among these

≈ 1.6M–2.7M copies

≈ $12.5M–$20.1M after Steam's cut

from ~34k 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.

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

Best case: No Man's Sky at ≈ 17.5M–28.5M copies, ≈ $289.3M–$777.8M 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 Space (7 of 8) and Open World (5 of 8).
The winners: Winners here lead with Colony Sim + Base-Building, priced around $25.
When they shipped: The similar games span 2010 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).
