typical (middle half) 5.6M–7.9M

Games like Summerland

A typical game among these

≈ 5.6M–7.9M copies

≈ $42.2M–$131.5M after Steam's cut

from ~131k 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.

No genre covers most of these similar games. The closest is Open World (3 of 8), so its genre is hard to place.

Of the 416 indie games that passed 1,000 reviews in 2022, 11.8% were novel genre mixes and 88.2% stuck to an established genre. Published indie market research.

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.

The genre you'd be entering

These games: The similar games share Open World (3 of 8) and Dark Fantasy (2 of 8).
The winners: Winners here lead with Open World, priced around $30. The breakout hits carry Open World + Singleplayer + Post-apocalyptic; a typical game here doesn't.
When they shipped: None of the similar games shipped in the last two years; the newest is from 2018. That says more about which games were found than about the market.

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 38 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).
