Genuinely great 400 positive and 400 negative reviews analyzed · data as of 2026-10-12

Summary

The adjusted rating for Factorio is 97.5% (95% range 97.4–97.6%), in line with the official 97.5% on Steam. It is based on 400 positive and 400 negative reviews weighted by trust. Verdict: "Genuinely great" (the adjusted rating is 70% or higher and the positive reviews carry high average trust).

Average trust is 0.78 for positive and 0.80 for negative reviews, but the gap is too small to move the official rating much. The most common discount factor is very short reviews, at 38% of all reviews.

The monthly history (129 months) has no month where volume and negative share jumped together. The rating does not appear to be driven by a single episode.

The last 180 days show 97.4% (last 30 days: 97.0%), close to the all-time figure.

Japanese-language reviews (1,650) show 97.2%, close to the overall rating. In the last 180 days, Japanese-language reviews show 96.0%.

The adjusted rating estimates trust from how reviews are written; it does not judge any individual review as fake. Data as of 2026-10-12.

Positive vs negative breakdown
