A typical game among these

≈ 186k–227k copies

≈ $987k–$1.4M after Steam's cut

from ~4k 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.

These similar games lean toward the genre's biggest winners; the typical figure comes from its ordinary successes.

Best case: Inscryption at ≈ 3.7M–6.0M copies, ≈ $20.3M–$54.6M 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 6k reviews in their first month; the range was 4k to 20k.

The genre you'd be entering

These games: The similar games share Puzzle (5 of 8) and Rogue-lite (4 of 8).
The winners: Winners here lead with Turn-Based Strategy + Turn-Based Tactics, priced around $17. The breakout hits carry Rogue-like + Deckbuilding + Story Rich; a typical game here doesn't.
When they shipped: The similar games span 2013 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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
