We know reviews aren't the best way to estimate sales, but it's still important to know what makes people write a review for your game, since reviews are an important factor on which the success of the game itself depends.
In this article, I will use sales estimates obtained from other estimation methods, as well as some publicly available sales data, to conduct in depth research into the sales/reviews ratio.
I will examine whether the following points affect the likelihood of players leaving a review. Release date - How does the release date affect the sales/review ratio? Price - Do more expensive games have a higher chance of getting a review? % positive reviews - Do players prefer to leave negative or positive reviews? Genres - Do some genres have a better chance of getting a review than others? Play time - Does longer playing time increase the chance of player writing a review? Demographics - Do player demographics affect the sales/review ratio? Audience - How does the audience affect the ratio? Number of reviews - Do more popular games have a lower or higher chance of getting reviews? AAA vs. indie games - Do indie games have a better chance of getting reviewed than AAA games?
This article will expand on previous research by Simon Carless in 2020 and VG Insights in 2021.
