But in general, it's not obvious that this is a reliable indicator. Some people go to a forum to chat about the game, while others just play without using any forums. How can we find out if the percentage of forum users compared to the total number of players is the same for two games? In particular, if a game is rarely played without mods (your X Rebirth doesn't have high ratings, so combined with your information about modding, I think I'm right), then the community activity, all other things being equal, will obviously be higher.
