I&#8217;ve always suspected that BoardGameGeek&#8217;s rating system is slightly biased towards heavier games, meaning that users tend to give higher ratings to the heavier, &#8220;gamer&#8217;s games&#8221;, and consequently lower ratings to lighter family and party games. I looked at data from 350 thousand games in BGG&#8217;s database, then filtered out games with fewer than 100 rating votes and games without a weight rating. Below is a two dimensional histogram, or heatmap, of the weights and the ratings.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c10e635 elementor-widget elementor-widget-image\" data-id=\"c10e635\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<style>\/*! elementor - v3.6.8 - 27-07-2022 *\/\n.elementor-widget-image{text-align:center}.elementor-widget-image a{display:inline-block}.elementor-widget-image a img[src$=\".svg\"]{width:48px}.elementor-widget-image img{vertical-align:middle;display:inline-block}<\/style>\t\t\t\t\t\t\t\t\t\t\t\t<img width=\"640\" height=\"480\" src=\"https:\/\/gflima.net\/wp-content\/uploads\/2022\/08\/heat_map-1.png\" class=\"attachment-large size-large\" alt=\"\" loading=\"lazy\" srcset=\"https:\/\/gflima.net\/wp-content\/uploads\/2022\/08\/heat_map-1.png 640w, https:\/\/gflima.net\/wp-content\/uploads\/2022\/08\/heat_map-1-300x225.png 300w\" sizes=\"(max-width: 640px) 100vw, 640px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-58b1e89 elementor-widget elementor-widget-text-editor\" data-id=\"58b1e89\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>We can see and upward trend quite clearly.

This makes sense, since we&#8217;re limiting some other factors that might influence the quality of the games.<\/p><p>But are users giving higher ratings to heavier games just because they&#8217;re heavier, or does the weight actually make the game better? It&#8217;s impossible to say for sure just by looking at this data. I&#8217;m of the opinion that complexity for complexity&#8217;s sake does not add quality to a game, yet it&#8217;s not unthinkable that heavier games might yield a more involved gaming experience, which can be seen as enhancing its overall enjoyment. But then I look at fairly light yet deep games such as <span style=\"color: #3366ff;\"><a style=\"color: #3366ff;\" href=\"https:\/\/boardgamegeek.com\/boardgame\/128882\/resistance-avalon\">The Resistance: Avalon<\/a><\/span>. There are many such games which, as far as rules go, are incredibly light but offer highly complex game states for the players to untangle and usually involve a non-trivial amount of emotional investment &#8211; and yet these tend to under perform in terms of user ratings.<\/p><p>Now here&#8217;s thought experiment, we could try to see what would happen to a game&#8217;s rating if we were to subtract the influence of its weight. By doing this we could see which is the best &#8220;pound for pound&#8221; game, much like the <span style=\"color: #3366ff;\"><a style=\"color: #3366ff;\" href=\"https:\/\/en.wikipedia.org\/wiki\/Wilks_coefficient\">Wilks coefficient<\/a><\/span> for powerlifting which subtracts the influence of body mass from each athletes performance. If we did this using our liner regression, given a game with rating <em><strong>r<\/strong><\/em> and weight <em><strong>w<\/strong><\/em>, its weightless rating <em><strong>r&#8217;<\/strong><\/em> is given by the formula<\/p><p style=\"text-align: center;\"><strong><em>r&#8217; = r &#8211; 0.66w<\/em><\/strong><\/p><p>Using the above equation we arrive at the unsettling result of <span style=\"color: #3366ff;\"><a style=\"color: #3366ff;\" href=\"https:\/\/boardgamegeek.com\/boardgame\/147949\/one-night-ultimate-werewolf\">One Night Ultimate Werewolf<\/a> <\/span>having a higher &#8220;weightless&#8221; rating than <span style=\"color: #3366ff;\"><a style=\"color: #3366ff;\" href=\"https:\/\/boardgamegeek.com\/boardgame\/174430\/gloomhaven\">Gloomhaven<\/a><\/span>&#8230;<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-db31e78 elementor-widget elementor-widget-heading\" data-id=\"db31e78\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Do games with miniatures get higher ratings?<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-233ccb9 elementor-widget elementor-widget-text-editor\" data-id=\"233ccb9\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Again, the short answer is yes, but there&#8217;s nuance.<\/p><p>Analyzing the impact of miniatures on ratings is fairly straightforward since this variable is binary, i.e. we have two disjoint classes: games with miniatures and games without miniatures. Looking at 350 thousand games and again, filtering out those with fewer than 100 ratings we see that the average (mean) rating of games with miniatures is 7.5 (std 0.7), which is significantly higher than of games without miniatures, which is 6.8 (std 0.9).<\/p><p>Here&#8217;s a density histogram for the ratings of each class.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4124cbc elementor-widget elementor-widget-image\" data-id=\"4124cbc\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img width=\"730\" height=\"561\" src=\"https:\/\/gflima.net\/wp-content\/uploads\/2022\/08\/histogram_rating_minis.png\" class=\"attachment-large size-large\" alt=\"\" loading=\"lazy\" srcset=\"https:\/\/gflima.net\/wp-content\/uploads\/2022\/08\/histogram_rating_minis.png 730w, https:\/\/gflima.net\/wp-content\/uploads\/2022\/08\/histogram_rating_minis-300x231.png 300w\" sizes=\"(max-width: 730px) 100vw, 730px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-98a0709 elementor-widget elementor-widget-text-editor\" data-id=\"98a0709\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Now, it could be the case that this has nothing to do with plastic components, and what&#8217;s actually happening is that games with miniatures tend to be heavier, and as we have seen before, heavier games get higher ratings. So if we now control for weight, and look at games with weight between 2 and 3, we see that the average (mean and median) weight for games with miniatures and for games without miniatures is 2.6 and 2.4, respectively, but the mean ratings are 7.4 and 7.0.
