“Just this past weekend my D mentioned D&D was being put on resumes”
I think it’s fine to put it on resumes in the “Additional Information/Personal” section at the end of the resume so interviewers get a feel for your personality, what you like to do in your free time, etc. However, it should not be a highlight of your accomplishments/skill sets as it has a stigma of being primarily role-playing entertainment, played by introverts and dare I say nerds.
