Troy is a horrible human being. As a GM, though, he has a few tricks up his sleeve, from finishing on cliffhangers to asking players how their characters are feeling about a particular situation. In contrast to other well-known GMs, he isn't afraid to kill, meaning that he actually ends characters. This keeps tension high and players on their toes. I'm not afraid to admit I've borrowed some of his ideas.
In contrast to some other shows out there, this really feels like a couple of friends playing. It's incredibly entertaining, while not being too far removed from your own home game. I cannot recommend it enough.
