I found a little gem on Netflix one day. The movie: Gamers: Dorkness Rising
The movie is everything you would expect from an independent team of writers and directors. It has all the snark and seriousness of gamers at a table. Although I am not a table top RPG player myself (gasp) I know what it is like to play Risk with my friends and family. I KNOW the type of table talk that comes out. When you get around to 3 am, the snark starts to fly.
I highly recommend you check it out. The snark about charisma alone is worth the watch.
