The following are issues that may be related to problems with article sizes. Some of the many problems with large articles that could cause problems with uploading speed, technical issues, readability, and so on.
It has sometimes been suggested that no article passes 32 KB in size, and while some articles on Nintendopedia are larger, notably Super Smash Bros. Brawl, they can be handled in a way so that it doesn't get out of hand. Mainly what I'm referring to is readability - Sometimes if you're searching through an article that has no sections, then it could be quite hard to find what you're looking for. For example, lets say you wish to find information on the items that are featured in Brawl. Currently, we have a section on the Brawl page that is dedicated to items, thus making it easy for a user to find what they're looking for quickly.
It's also asked that on some articles that require it, such as the Brawl's item section, that you add sub-sections that talk even more about the subject in question. For example - Brawl has a wide range of different types of items, including standard items, assist trophies, and Pokéball Pokémon, as well as some other related things such as collectible items. The three latter mentioned subjects can thus have their own sub-section, which makes finding what someone is looking for even easier.
Even pages such as Goomba, which are, compared to the Brawl page, relatively small; need sections so that navigating the article is easy.
However, it may be hard to find a certain point to seperate the article into sections. Nevertheless, it's asked that you try your best to find one.
Also, if a page gets dramatically larger than what is asked of, then it may be time to move certain parts of the article into seperate pages, rather than sections, seeing that load times can take a considerably long time when trying to access a page such as Wikipedia's "List of Unicode characters", which exceeds over 380,000 KB.
