What can I do as a career, or volunteering position , that uses Dungeons and Dragons role playing game?

You can’t outside of streaming youtube videos about it.

@ARE_you_kidding_me Is it trademark infringement? I guess Yatzee is fair use. In the hospital we played super smach brothers and wii bolwling.

Start a business that hosts game nights I suppose. Really, not a career choice.

work at a gaming store.

From the little I know about role playing games, that sounds like a great idea. I did a Web search on occupational therapy and Dungeons and Dragons, and came across this link among several others.

You should go beyond fantasizing and actively pursue this. D&D is something you are familiar with, and you would be able to help others and, in so doing, help yourself. Maybe you could contact some local hospitals and offer your services.

Volunteer to lead game afternoons at the local recreation department.
