I included WoW specifically to show some of the issues with this method of comparison, namely that some things will have much higher online interest than interest in real life and that for some particular topics, if you are interested in the topic, you will need to google the topic a lot. WoW is an example of both of these. If you play the game, you will need to spend a lot of time referring to articles and videos created by many different people on multiple websites and thus this will result in more than just a single search query. Minecraft would be another example of a game like this, as Minecraft is essentially a wiki game where almost all the information required to play is located on the wiki.
WoW is almost certainly not as big as Star Wars, despite appearing as such on that graphic. In the link you included btw, all the searches for BG 3 are included in the BG topic.
