Did the prediction match what actually happened?

We hid System Shock and predicted how it would do from its 8 similar games. Every figure here, including System Shock's, is estimated from Steam reviews.

Copies, estimated from reviews

typical (middle half) 7.5M–10.1M

best case 32.0M (Cyberpunk 2077)

Games like System Shock

A typical game among these

≈ 7.5M–10.1M copies

≈ $37.6M–$121.2M after Steam's cut

from ~200k 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 178k reviews in their first month; the range was 57k to 326k.

The genre you'd be entering

These games: The similar games share Open World (6 of 8) and FPS (3 of 8).
The winners: Winners here lead with Open World, priced around $40. The breakout hits carry Cyberpunk + Nudity + RPG; a typical game here doesn't.
When they shipped: The similar games span 2012 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).
