Games like ISLAND

A typical game among these

≈ 2.4M–3.7M copies

≈ $16.9M–$64.2M after Steam's cut

from ~88k 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 3 of the similar games are hits.

This comes from a small set of games, so take it as a sketch.

Best case: Persona 5 Royal at ≈ 3.5M–5.7M copies, ≈ $57.7M–$155.1M after Steam's cut.

What their first month looked like

About half the games that made it here had over 11k reviews in their first month; the range was 7k to 19k.

The genre you'd be entering

These games: The similar games share Anime (3 of 3) and JRPG (2 of 3).
The winners: Winners here lead with JRPG + Story Rich, priced around $60.
When they shipped: None of the similar games shipped in the last two years; the newest is from 2022. 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).
