A few additional pointers regarding the applicable infoboxes and categories:
The applicable infobox for quest pages is {{Infobox quest}}. For games which feature achievements and trophies, {{Infobox achievement}} is also inserted directly below the quest infobox. For details on their usage, please refer to the template page itself.
A quest page is only categorized in one category. The category depends on the game it appears in (e.g. Category:Fallout quests). A further distinction should be made if it is an unmarked quest, i.e. a quest which does not appear in the quest log (e.g. Category:Fallout unmarked quests).
Quest article layout
The layout is composed of three tables. The top and bottom tables are standard layout items found in every article; they are only included here for completeness and are collapsed by default. The middle table contains the actual specifics for quest pages.
in the "headline" column means that the article should have a headline of that name if you want to include such a layout item. in the "headline" column means that this layout item should not have a headline.
in the "required" column means that every quest article should include this layout item. in the "required" column means that not every quest article needs to include this layout item.

Explanation
Page management boxes
Page management templates are used if you notice that something is out of order with a certain article or section and want to bring it to the attention of other editors or administrators. If the issue affects the whole article, these boxes should be placed at the very top of an article; if only a section is affected, they should be placed just below the headline of the respective section. The only exception are stub templates.
Projects are joint efforts of editors who work together to improve a set of articles that cover a certain area of interest. Some of these projects have tags or boxes which are placed on the pages which the project affects; these should be placed below the article management boxes.
"For" template
{{for}} is used to make a reader aware of other articles they may have been looking for when entering the title of the current page.
Infobox
The purpose of infoboxes is to summarize data relating to the article. Infoboxes should appear in the top-right corner of an article. For a list of infobox templates, please refer to template overview or directly to Category:Infobox templates.

Game glitches or "bugs" relating to the article subject. See bugs policy for additional information.
Gallery

Videos
If an article contains embedded videos, they are placed here. See video policy for which kind of videos are eligible to be placed in articles.

Navboxes
Navboxes are navigational aids which allow easy access to other articles in a group the current article belongs to. They should be placed at the end of an article, just above the categories. The most article-specific navboxes should be highest and the least-specific lowest.
