Story Rich

Sales estimates

Paid-game estimates use the same transparent multi-factor Boxleiter method. Free-to-play games never receive paid unit or revenue estimates.

Sales estimate

v1.0

20.5M to 47.8M

units (median: 34.2M)

≈ $351.1M to $819.3M modeled net revenue (fixed store-cut, refund, and regional-price assumptions applied)

Heuristic display range: median × [0.6, 1.4]. Boundary protection: NB ∈ [15, 150].

Methodology & limitations

Sales estimates use an additive Boxleiter-derived heuristic against public Steam review counts. They are not authoritative sales data, and the fixed display range is not a statistically validated confidence interval. Actual results may fall outside it, especially for deeply discounted or bundle-heavy titles. Algorithm version v1.0. Read the exact method and validation status.

How comparison pages work

Verdicts are objective, they call out which game scores higher on a single measurable axis (reviews, price, sales estimate, recency). They don't claim "better." Tag overlap is computed from the public Steam tag list. Sales estimates use a multi-factor Boxleiter method whose formula is shown in full on each game's page.

Want a comparison that doesn't exist? Browse all games, find two slugs, and concatenate them: /compare/games/<slug-a>/<slug-b>. Both orderings render the same content; we canonicalise to alphabetical for SEO.
