How much revenue did SOS make?

SOS is free to play, so there is no copy-sales revenue to estimate.

How many copies did SOS sell?

Q: How many copies did SOS sell?

204k to 332k copies, based on its 7k Steam reviews. This is a labeled estimate from the review count, not exact sales.

Estimated copies sold: ≈ 204k–332k; from 7k reviews (Mostly Negative)

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

Copies, estimated from reviews

typical (middle half) 781k–14.8M

Games like SOS

A typical game among these

≈ 781k–14.8M copies

from ~78k 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: PUBG: BATTLEGROUNDS at ≈ 95.8M–155.7M copies.

The genre you'd be entering

These games: The similar games share Battle Royale (8 of 8) and Survival (7 of 8).
The winners: Winners here lead with Survival + Shooter.
When they shipped: None of the similar games shipped in the last two years; the newest is from 2020. That says more about which games were found than about the market.

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 43 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
