Games like Prototype 2

A typical game among these

≈ 590k–1.0M copies

≈ $4.7M–$10.9M after Steam's cut

from ~14k reviews

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

7 of the 8 similar games are hits.

Best case: Red Dead Redemption 2 at ≈ 26.6M–43.2M copies, ≈ $438.4M–$1178.6M after Steam's cut. It is a breakout hit, far above a typical game.

The genre you'd be entering

These games: The similar games share Open World (5 of 8) and Superhero (5 of 8).
The winners: Winners here lead with Open World, priced around $40. The breakout hits carry Open World + Western + Realistic; a typical game here doesn't.
When they shipped: The similar games span 2009 to 2024, and 1 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).
