We don't need categories with 1 item only. We have Year category for Editins, Characters and Hoverboard. I'll include tokens as well. The event pages, as they are only 1 per year, are being categorized under "Events".
I would't include the events pages on the same year category as Edition, Characters and other game-core things, but if you like, we could do it.
Did you noticed that by undoing my update on CharacterBox' template you are crashing all the characters articles?
If you don't like something in what I'm doing, you can always talk to me and then we can create better things together.
Undoing is nothing productive and you're slowing me.
