Estimated copies sold
≈ 223–363
$919–$2k after Steam's cut $2k–$4k before the cut
from 9 reviews (9 user reviews)
Thin evidence: 9 reviews. That range swings on one or two people, so read it as a hint, not a measurement.

A labeled estimate from the public review count (adjusted for release year), not exact sales. Owner data cross-checked with SteamSpy.

Only the top fifth of 2019’s Steam releases earned about $34k gross, so plan for that or less.

2 of your 8 similar games are hits.

Best case: BlazBlue Entropy Effect at ≈ 898k–1.5M copies, ≈ $4.9M–$13.3M after Steam's cut. A breakout hit, far above a typical game.

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).
