Games like Grunn

A typical game among these

≈ 743k–1.2M copies

≈ $4.3M–$16.8M after Steam's cut

from ~35k 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: Undertale at ≈ 16.8M–27.2M copies, ≈ $46.0M–$123.8M 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 4k reviews in their first month; the range was 332 to 11k.

The genre you'd be entering

These games: The similar games share Choices Matter (7 of 8) and Story Rich (7 of 8).
The winners: Winners here lead with Story Rich + Choices Matter, priced around $10. The breakout hits carry Great Soundtrack + RPG + Pixel Graphics; a typical game here doesn't.
When they shipped: The similar games span 2015 to 2023, and none of them 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 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
