It was at 80% after the first week, then then down to 75% after 4 weeks, then there was a 7 day period at the end of November which saw 8,084 positive reviews & 283 negative reviews - 8,367 total reviews with a 97% positive rating - which bumped the overall score to 83%. I'm not sure why, or even how, Civ VI had such an overwhelmingly good week when the 7 days after had 421 reviews at 60% positive and the 7 days prior had 612 reviews at 69% positive. Anyway, after it had 83% after 6 weeks, it steadily fell for the next 94 weeks to 66%. Then managed to start climbing again after another 50 weeks.
What is weird is that the last week of November always saw a massive influx of reviews in comparison to the week before and after which were insanely positive:
- Week of November 24th 2016 - 8,376 reviews, 97% positive
- Week of November 23rd 2017 - 1,965 reviews, 95% positive
- Week of November 20th 2018 - 3,495 reviews, 92% positive
- Week of November 19th 2019 - 1,083 reviews, 99.8% positive
These 4 weeks are 27% of all positive reviews in the first 3 years. I'm not sure why this is. A SteamDB error? Users being prompted to give reviews on Steam? Fake reviews?
