To celebrate "The Mighty Nein," we had the Critical Role cast — Laura Bailey, Travis Willingham, Matthew Mercer, Ashley Johnson, Marisha Ray, Taliesin Jaffe, Sam Riegel, and Liam O'Brien — compete in a game of Cast Wars to see who knows their three campaigns the best. It's competitive. It's hysterical. Watch it all now! #CriticalRole #TheMightyNein
