≈ 830–1k copies

≈ $2k–$5k after Steam's cut

from ~26 reviews

Only the top fifth of 2019's Steam releases earned $34k or more before Steam's cut, so plan for that or less.

1 of the 8 similar games is a hit.

These similar games lean toward the genre's biggest winners; the typical figure comes from its ordinary successes.

Best case: My Lovely Daughter at ≈ 40k–65k copies, ≈ $165k–$442k after Steam's cut. 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 46 reviews in their first month; the range was 10 to 121.

Games with under about 100 reviews in month one almost never recover.

The genre you'd be entering

These games: The similar games share Villain Protagonist (7 of 8) and Choices Matter (4 of 8).
The winners: Winners here lead with Villain Protagonist, priced around $15. The breakout hits carry Multiple Endings; a typical game here doesn't.
When they shipped: The similar games span 2017 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 43 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
