From GamingWiki
Use this template to indicate that the current page represents a campaign. The syntax for this is:
{{Campaign
| status = active or inactive
| system = Game System Name
| genre = Genre(s) separated, by commas
| image = [[File: Image name.jpg]]
| volume label = Volume (default)
| book label = Book (default)
| chapter label = Chapter (default)
}}
There is no support for explicitly setting the campaign name -- the template will take the name of the page on which it is found. This limitation is by design.
