he’ll be visiting the team at Critical Role as their Game Master for the next core campaign of the tabletop role-playing game, actual-play series’.
That's the actual quote from the article. It could be implying that Brandon is taking over the next campaign, but to me it sounds like he'll be visiting as an occasional GM the same way he did for events around campaign 3. That's cool, I think. The entire crew thrives on collaboration.
I guess I didn't navigate the ads properly to the end of the article. Thanks for clarifying. We'll see how it pans out. I don't think Matt needs to be the forever GM for the crew to be successful. And it's nice to see Mercer get a chance to do some deeper role playing a single character instead of a handful of shallower NPCs.
