Wikia is a generic Wiki creation site. This is one of those wikis.
Wikia has just one disadvantage: the "read more" can be odd. For example, you may add a category to Mama Luigi, but the read more sometimes includes only one of those categories (e.g., "gay" may make it include all gays). However, otherwise, it is good. You can Link articles and create categories, add videos and pictures, etc. However, place the pics in the right places or else the icon for it will just be the article's words.
Like YouTube, Wikia is always changing its format, often ruining things. Thumbnails are the most common things. The required size for a thumbnail to work has always gotten bigger (chances are this article won't have a thumbnail), and now the thumbnail is simply just compressed, which is really annoying.
