322 to 524 copies, based on its 13 Steam reviews. This is a labeled estimate from the review count, not exact sales.

Did the prediction match what actually happened?

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

Copies, estimated from reviews

typical (middle half) 1k–3k

best case 10k (Mercury Fallen)

Games like UDO

A typical game among these

≈ 1k–3k copies

≈ $3k–$8k after Steam's cut

from ~61 reviews

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

None of the 8 similar games are hits.

Best case: Mercury Fallen at ≈ 8k–13k copies, ≈ $55k–$147k 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 27 reviews in their first month; the range was 8 to 212.

Games with under about 100 reviews in month one almost never recover.

The genre you'd be entering

These games: The similar games share Exploration (5 of 8) and Action-Adventure (2 of 8).
The winners: Winners here lead with Sci-fi + Management, priced around $25. The breakout hits carry Sci-fi + Isometric + Colony Sim; a typical game here doesn't.
When they shipped: The similar games span 2018 to 2025, and 3 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 38 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
