- The number of reviews on Steam games is increasing every year. In 2013, there were 93 copies sold per review, while in 2023, there were 32 copies sold per review.
- The more discounts, the fewer reviews. Up to an average discount size of 20%, there is no correlation (on average, 1 review per 34-35 copies). However, once the average discount size increases to 30% and higher, there are between 40 to 57 copies sold per review.
- Games with negative (up to 50% positive) reviews receive a lot of reviews – 24-39 sales per review. Games with a very high (close to 100%) number of positive reviews result in 25 copies sold per review similarly. This is apparently because people either want to share their dissatisfaction or tell others about the wonderful game they played.
- The more a person plays a game, the higher the probability that they will leave a review.
- For niche games (up to 100 reviews) and hits (100,000 reviews and more), there is roughly the same conversion to reviews (1 review per 36-38 copies).
