How many copies did Ultimate Protector sell?

Estimated copies sold
≈ 2k–3k
$1k–$3k after Steam's cut $2k–$5k before Steam's cut
from 63 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 Ultimate Protector and predicted how it would do from its 8 similar games. Every figure here, including Ultimate Protector's, is estimated from Steam reviews.

Copies, estimated from reviews

typical (middle half) 268–562
best case 1.2M (BlazBlue Entropy Effect)
Games like Ultimate Protector

A typical game among these

≈ 268–562 copies

≈ $207–$970 after Steam's cut

from ~11 reviews

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

2 of the 8 similar games are hits.

Best case: BlazBlue Entropy Effect at ≈ 908k–1.5M copies, ≈ $5.0M–$13.4M 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 7 reviews in their first month; the range was 1 to 14k.
Games with under about 100 reviews in month one almost never recover.
The genre you'd be entering
These games
The similar games share Action Roguelike (5 of 8) and Tower Defense (5 of 8).
The winners
Winners here lead with Platformer + Replay Value, priced around $20. The breakout hits carry Replay Value + Platformer + Difficult; a typical game here doesn't.
When they shipped
Only 3 of the 8 similar games shipped in the last two years. 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 of about 31, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
