Namespaces are different from categories—Category:Community does have Category:Groups as a subcategory. While moving group pages to the Community namespaces might seem to make sense given the namespace's name, it doesn't make sense given its purpose, which was to contain pages about players and places only. I suggested "Community" as a name only because that sounded better than "Players" for a namespace name.

I fixed categorization of games made by groups. I thought I had already fixed it, but I had forgotten to make Module:PlaceInfobox categorize pages in the main namespace as I did with Module:ItemInfobox.
