≈ 895–30k copies

≈ $2k–$31k after Steam's cut

What their first month looked like

About half the games that made it here had over 24 reviews in their first month; the range was 1 to 243.

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

The genre you'd be entering

These games: The similar games share Anime (6 of 8) and Visual Novel (6 of 8).
The winners: Winners here lead with Visual Novel + Psychological Horror, priced around $1.
When they shipped: Only 1 of the 8 similar games shipped in the last two years. 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 of about 31, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
