Story:

Game Designer travels to Oxford to live while designing a RPG epic. Drinks regularly at the Eagle and Child and working on his design there - a form of "studying under the masters." (a la Louvre in France.)

After a while there, a local introduces himself to Game Designer, asking if what he's working on is D&D. "I suppose it is, in a matter of speaking." GD invites him for a drink and talks for a while - getting to know him. Local confesses that he and his friends are a group of D&D players without a DM - and they've been dying for a game. GD confesses to being rather lonely and would welcome the company of gamers and hopefully new friends.

Local introduces GD to friends, they all get to know each other. GD agrees to DM his game for them. Everyone is happy, game happens.

At least one of the gamers is a female - introduce love interest. Story follows game development/progression, friendship, love and cultural displacement. Uses location well - Oxford (for Christ sake.)

Bonus! End of movie/story/whatever follows with release of epic RPG game!
