A typical game among these

≈ 293–32k copies

≈ $701–$184k after Steam's cut

from ~39 reviews

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

2 of the 8 similar games are hits.

No genre covers most of these similar games. The closest is Real Time Tactics (4 of 8), so its genre is hard to place.

Of the 416 indie games that passed 1,000 reviews in 2022, 11.8% were novel genre mixes and 88.2% stuck to an established genre. Published indie market research.

Best case: Red Solstice 2: Survivors at ≈ 82k–134k copies, ≈ $339k–$912k after Steam's cut.

What their first month looked like
About half the games that made it here had over 10 reviews in their first month; the range was 1 to 2k.

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).
