The middle of these games

≈ 191k–289k copies

≈ $2.1M–$6.9M after Steam's cut

from ~6k 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: Persona 5 Royal at ≈ 3.4M–5.6M copies, ≈ $56.7M–$152.4M after Steam's cut. A breakout hit, far above a typical game.

What it took to get here

About half the games that made it here had over 3k reviews in their first month; the spread ran 2k to 14k.

The genre you'd be entering

Your set: Your set clusters on JRPG (7 of 8) and Anime (6 of 8).
The winners: Winners here lead with JRPG + Story Rich, priced around $60. The breakout hits carry Dating Sim + Story Rich + Great Soundtrack; a typical game here doesn't.
The era: The games you compared span 2014 to 2024, and 1 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).
