Games like 9-nine-:Episode 3

A typical game among these

≈ 1.4M–2.0M copies

≈ $6.0M–$14.2M after Steam's cut

from ~49k 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.

Best case: Doki Doki Literature Club! at ≈ 7.9M–12.8M copies. It is a breakout hit, far above a typical game.

What their first month looked like

About half the games that made it here had over 12k reviews in their first month; the range was 2k to 27k.

The genre you'd be entering

These games: The similar games share 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.
When they shipped: The similar games span 2014 to 2024, and 2 of the 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).
