≈ 100k–150k copies

≈ $353k–$797k after Steam's cut

from ~3k reviews

Only the top fifth of 2019’s Steam releases earned about $34k gross, so plan for that or less.

All 8 of your similar games are hits.

Your picks lean toward this genre's biggest survivors; the typical figure reads from its ordinary successes.

Best case: Helltaker at ≈ 3.2M–5.2M copies. A breakout hit, far above a typical game.

What it took to get here
About half the games that made it here had over 13k reviews in their first month; the spread ran 790 to 21k.
The genre you'd be entering
Your set
Your set clusters on Detective (6 of 8) and Visual Novel (6 of 8).
The winners
Winners here lead with Demons + Puzzle, priced around $20. The breakout hits carry Anime + Great Soundtrack + Singleplayer; a typical game here doesn't.
The era
The games you compared span 2014 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 70 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
