Best Way to Set Up a multi-adventure Campaign?

Hi! I did a quick search in the forums, but couldn't find a topic that seemed to tackle this.  Is there a best way to set up a Game where I can continue to add purchased content, rather than creating a new game for each purchased adventure (e.g., SKT, CoS, ToA, etc.)? Ideally I would like the ability, within the same Game, to go back to maps, info, journals, etc. from previous adventures to maintain a living world. Is this possible, or will I have to use some combination of creating a new game and Transmogrifier and/or Copy/Extend Game (which I don't know a lot about... I just know they are tools that seem to copy some/all info from one Game to another)? My thanks!

Any Marketplace content sold as an Addon can be added to an existing Game from the Game Settings page. Any Marketplace content sold as a Module must be used as the basis for a newly created game.  If you have access to the Transmogrifier (Pro level perk) you can move content from that new game into an existing game.

It is not a bad idea to make two games if the creator has a pro subscription and you can use the Transmogrifier. That way you can create and test stuff and port it over when it is working as you want it. You will keep the running game trim and fit and running as quickly as possible.

Sorry for the late reply (busy week / weekend), and my thanks The Aaron & al e.
