Games like Monument

A typical game among these

≈ 281k–943k copies

≈ $2.4M–$5.2M after Steam's cut

from ~10k 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: ULTRAKILL at ≈ 6.1M–9.9M copies, ≈ $50.2M–$134.8M 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 2k to 7k.

The genre you'd be entering

These games: The similar games share FPS (8 of 8) and Boomer Shooter (7 of 8).
The winners: Winners here lead with Boomer Shooter + Fast-Paced, priced around $30. The breakout hits carry Blood + Character Action Game + Spectacle fighter; a typical game here doesn't.
When they shipped: The similar games span 2007 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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
