Games like Retrograde Arena

A typical game among these

≈ 239k–394k copies

≈ $1.5M–$1.8M after Steam's cut

from ~7k 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: Enter the Gungeon at ≈ 3.7M–6.1M copies, ≈ $15.4M–$41.5M 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 2k reviews in their first month; the range was 409 to 7k.

The genre you'd be entering

These games: The similar games share Bullet Hell (7 of 8) and Twin Stick Shooter (6 of 8).
The winners: Winners here lead with Bullet Hell + Action Roguelike, priced around $15. The breakout hits carry Difficult + Dungeon Crawler + Local Co-Op; a typical game here doesn't.
When they shipped: The similar games span 2010 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).
