I'm not sure if you plan on making features like this, but I will suggest it anyway.

In SquareSpace, they have a really nice way of displaying all the categories and the things nestled in each category automatically. It makes for a really easy way to navigate the wiki and a nice homepage. I know of one instance in a mobile game and will attach a picture. The orange text is the category, and the links under it are pages that have been tagged with said category.

I did find this: https://requests.requarks.io/wiki/p/tagging-system so maybe you already have something like this planned. For a gaming wiki it would be extremely useful.
