@glennmagusharvey Predates the big chatGPT push iirc. THey have a limited set of tags and they have their own algorithm ideas of what tags most commonly go together and what might be related to the description you put on the game webpage, so they suggest ideas for you to pick from.
Some devs will just 'sure whatever' and take all of them. Or not even know what they MEAN. If you're not a genre expert in some of these tags you may not understand them.
