You have been warned multiple times not to add unnecessary categories to pages. We have also told you to ask an administrator before adding categories to pages, since almost all of the categories that you have added since your joined have been unnecessary.
Do not do this again. This is your final warning before you are blocked for a week.
It's basically a first come first serve basis. If you have a chance to create customers, ingredients, specials, etc. for a new game, then you will be able to add categories. If you don't create pages, then it will take you a very very long time to earn a category badge (since I know that's what you're trying to do).
To earn the category badges, you must do work. If you don't do work, you won't get the badges. It's as simple as that.
As the other admins have stated to you. Don't just do stuff to earn badges around here. It's not against the rules, but it's not fair either. You have to earn them properly (if you want to get any kind of respect around here).
That said, if you're planning on earning this badge, make whatever comments you type count. Not just a one-word comment or a short sentence. If you're going to earn badges, make them worth it. Quality over quantity.
