Games like Deadly Days

A typical game among these

≈ 5.6M–6.6M copies

≈ $54.7M–$69.6M after Steam's cut

from ~163k 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: Don't Starve Together at ≈ 22.6M–36.8M copies, ≈ $93.2M–$250.7M 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 73k reviews in their first month; the range was 42k to 129k.
The genre you'd be entering
These games
The similar games share Action Roguelike (5 of 8) and Rogue-like (4 of 8).
The winners
Winners here lead with Action Roguelike + Rogue-like, priced around $15. The breakout hits carry Indie; a typical game here doesn't.
When they shipped
The similar games span 2014 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 70 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
