Is there a way to do this? I purchased several Call of Cthulhu modules in a bundle and I am sifting through them to figure out which I want to include in a small campaign, but the only way I can find to view the content is to create a game. Is there another option?
Probably not. Most likely, the adventure information will be in handouts, which are only viewable once a game is created. Once you have created a game, you should be able to view handout content through the external journal without actually needing to log into the game. The only way you could view adventure content without making a game would be if the adventure outline/text is part of compendium content, and I don't think they are usually set up that way.
Yeah, the adventure text was included in some very early module conversions until it was realized that this would allow players to read the material. Nowadays, that stuff is carefully separated. The good news is that accounts have no limit on the number of games that can be created. It doesn't take anything from your storage quota.
I do similar. Another tip is to make careful use of the tagging system. I use keywords like module, addon, reference, backup, library, utility, [system], [sheet], hosted, API, and more. Good lord, I just counted. I have over 400 games.
