≈ $6.0M–$14.1M after Steam's cut

from ~49k 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.

Best case: Doki Doki Literature Club! at ≈ 7.8M–12.7M 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 12k reviews in their first month; the spread ran 2k to 27k.

The genre you'd be entering

Your set: Your set clusters on Dating Sim (7 of 8) and Visual Novel (6 of 8).
The winners: Winners here lead with Psychological Horror + Visual Novel. The breakout hits carry Psychological Horror + Horror + Free to Play; a typical game here doesn't.
The era: The games you compared span 2014 to 2024, and 2 of your 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 70 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
