This article is a quick overview on categorizing pages.
What not to doEdit
Do not add a base category to a page, such as adding Category:Crysis 2 to a page about content in Crysis. There are already subcategories that cover specific parts of a game, such as characters, vehicles, and weapons. Place pages in those categories instead. Placing pages in the base category simply clutters it and defeats the point, which is to link to other categories related to the page.
Do not add game-related categories to blogs. These are here to categorize game-related pages, not blogs, and are sometimes difficult to remove.
