| `Based on a Video Game`    | `video_games` | Collection of Movies/Shows based on or inspired by video games                 |

## Config

The below YAML in your config.yml will create the collections:

```yaml
libraries:
  Movies:
    collection_files:
      - default: based
  TV Shows:
    collection_files:
      - default: based
```

## Template Variables

Template Variables can be used to manipulate the file in various ways to slightly change how it works without having to 
make your own local copy.

Note that the `template_variables:` section only needs to be used if you do want to actually change how the defaults 
work. Any value not specified will use its default value if it has one if not it's just ignored.

??? abstract "Variable Lists (click to expand)"

    * **File-Specific Template Variables** are variables available specifically for this Kometa Defaults file.

    * **Shared Template Variables** are additional variables shared across the Kometa Defaults.

    * **Shared Separator Variables** are additional variables available since this Default contains a 
    [Separator](../separators.md).

    ```yaml
    libraries:
      Movies:
        collection_files:
          - default: based
            template_variables:
              sep_style: navy #(1)!
              use_comics: false #(2)!
              order_true_story: 01 #(3)!
              visible_library_video_games: true #(4)!
              visible_home_video_games: true #(5)!
              visible_shared_video_games: true #(6)!
    ```

    1.  Use the navy [Separator Style](../separators.md#separator-styles)
    2.  Do not create a "Based on a Comic" collection
    3.  Make the "Based on a True Story" collection appear in the collection list before the other collections in this 
    file
    4.  Pin the "Based on a Video Game" collection to the Recommended tab of the library
    5.  Pin the "Based on a Video Game" collection to the home screen of the server owner
    6.  Pin the "Based on a Video Game" collection to the home screen of other users of the server
