The little bit of data we have is that CR content could be one of the worst selling books.If Critical Role goes to Campaign 4 and runs it on Daggerheart - when it releases - it will be a big swing. You're underestimating the potential here. The Venn Diagram around the newest D&D players and Critical Role fans has a lot of overlap - and the newest players are the best source for expanding the brand. If you cut that smaller and spread it into Daggerheart instead....
I know we all have hunches, but it doesn’t quite appear that CR is a plus for selling TTRPG books compared to WotC’s regular content.
