How much revenue did Lemma make?

$50k–$135k after Steam's roughly 30% cut, derived from the copies estimate and its price.

How many copies did Lemma sell?

Q: How many copies did Lemma sell?

12k to 20k copies, based on its 250 Steam reviews. This is a labeled estimate from the review count, not exact sales.

Estimated copies sold: ≈ 12k–20k; $50k–$135k after Steam's cut $91k–$208k before Steam's cut; from 250 reviews (Very Positive)

Copies are estimated from the public review count, adjusted for release year, and cross-checked against SteamSpy's own estimate.

Did the prediction match what actually happened?

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

Copies, estimated from reviews

typical (middle half) 203k–1.3M

best case 3.7M (Dishonored 2)

Games like Lemma

A typical game among these

≈ 203k–1.3M copies

≈ $2.5M–$16.1M after Steam's cut

from ~12k 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: Dishonored 2 at ≈ 2.8M–4.5M copies, ≈ $23.0M–$61.8M after Steam's cut.

The genre you'd be entering

These games: The similar games share Female Protagonist (6 of 8) and First-Person (6 of 8).
The winners: Winners here lead with Stealth + First-Person, priced around $30.
When they shipped: The similar games span 2009 to 2021, 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).
