Did the prediction match what actually happened?

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

Copies, estimated from reviews

typical (middle half) 156k–240k

best case 7.1M (World of Warships)

Games like UBOAT

A typical game among these

≈ 156k–240k copies

≈ $902k–$2.9M after Steam's cut

from ~3k 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: World of Warships at ≈ 5.4M–8.8M copies. It is a breakout hit, far above a typical game.

The genre you'd be entering

These games: The similar games share Naval (6 of 8) and Naval Combat (6 of 8).
The winners: Winners here lead with Naval Combat + Co-op. The breakout hits carry Free to Play + Action + Tactical; a typical game here doesn't.
When they shipped: The similar games span 2006 to 2023, 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).
