Games like Three Days

A typical game among these

≈ 1k–3k copies

≈ $2k–$4k after Steam's cut

from ~37 reviews

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

None of the 8 similar games are hits.

Best case: Grindstone at ≈ 9k–14k copies, ≈ $47k–$127k 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 23 reviews in their first month; the range was 9 to 52.

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

The genre you'd be entering

These games: The similar games share Puzzle (7 of 8) and Arcade (6 of 8).
The winners: Winners here lead with Arcade + Puzzle, priced around $20. The breakout hits carry Hack and Slash + Collectathon + 2D; a typical game here doesn't.
When they shipped: The similar games span 2015 to 2025, 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 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
