Hmmm...I checked, and that's not what I see. It looks to me like whenever they play non-campaign stuff viewership plummets. Whether it is using D&D or another system (some of their non-D&D games are among their most popular one-offs).I cannot fathom Critical Role putting at risk their massive Prime Video contracts in order to keep a minority of their fans happy. Whenever they play non-D&D the viewership plummets.
Which makes sense - folks are naturally more inclined to want to keep up with a serialized story than a one-off, particularly when those one-offs often feature different casts.
This leaves open whether viewership would plummet if they switched the main campaign to, say, Pathfinder (where it began in their home game) or their potential home-made system.
