"So you want to make a TV show about role-playing and can't tear yourself away from the cliche' of a bearded man living in his parent's basement? Steal my pitch!
Jane is an event director at a retirement community. She is in charge of, you guessed it, planning events for the seniors. She has been successful with everything from bingo to balloon table hockey.
One day her boss, Sarah, informs her that their facility has been chosen for a pilot program to help troubled/at risk youth forced to volunteer at the retirement community. Jane struggles with finding an activity engaging enough for both the seniors and the teens. She recruits the help of her teenage child, Aaron/Erin, who is an avid RPG'er.
Aaron/Erin gives DM advise to Jane who runs sessions for the group of seniors and angsty teens. Who reluctantly (at first) form bonds over the course of game play.
It's a Golden Girls meets, that 70's show, meets Community.
You could replace Jane with John, who is a single dad trying to form a bond with Erin his teenage daughter."
