While Critical Role might have had humble beginnings as a group of friends simply playing Dungeons & Dragons together, their online presence started with a ton of support, including the show being live-streamed and produced by Geek & Sundry. However, in 2019, the show separated from Geek & Sundry, with the production company going into rapid decline soon after. It has been four years since this separation and Critical Role has seen rapid expansions since then, so newer fans might be wondering just why the separation happened.
