typical (middle half) 5.7M–16.9M

best case 32.0M (Cyberpunk 2077)

Games like Mass Effect 2 (2010 Edition)

A typical game among these

≈ 5.7M–16.9M copies

≈ $103.8M–$132.3M after Steam's cut

from ~154k 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: Cyberpunk 2077 at ≈ 24.4M–39.6M copies, ≈ $402.0M–$1080.8M 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 30k reviews in their first month; the range was 25k to 326k.

The genre you'd be entering

These games: The similar games share Open World (7 of 8) and Story Rich (7 of 8).
The winners: Winners here lead with Cyberpunk + Open World, priced around $60. The breakout hits carry Cyberpunk + Nudity + Sci-fi; a typical game here doesn't.
When they shipped: The similar games span 2010 to 2022, 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).
