A typical game among these

≈ 1k–7k copies

≈ $2k–$34k after Steam's cut

from ~63 reviews

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

1 of the 8 similar games is a hit.

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 27 reviews in their first month; the range was 3 to 2k.

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

The genre you'd be entering

These games: The similar games share FPS (8 of 8) and Boomer Shooter (6 of 8).
The winners: Winners here lead with Boomer Shooter + Fast-Paced, priced around $30. The breakout hits carry Blood + Retro + Character Action Game; a typical game here doesn't.
When they shipped: 6 of the 8 similar games shipped in the last two years. You'd be launching into a busy stretch.

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 of about 31, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
