Copies, estimated from reviews

typical (middle half) 3.4M–7.3M

Games like b

A typical game among these

≈ 3.4M–7.3M copies

≈ $24.4M–$62.2M after Steam's cut

from ~88k 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 Anime (4 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: Wallpaper Engine at ≈ 31.0M–50.3M copies, ≈ $42.5M–$114.3M after Steam's cut.

The genre you'd be entering

These games: The similar games share Anime (4 of 8) and Story Rich (4 of 8).
The winners: Winners here lead with Mature + Utilities, priced around $5.
When they shipped: None of the similar games shipped in the last two years; the newest is from 2019. 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 36 for the most recent game here to about 70 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
