The idea of players' choices actually setting events on the show into motion disturbs me. The storytelling on the show should be driven by the needs of the show and the characters, not by the random vagaries of gameplay. I'm hoping that the interaction is more just an illusion -- that there's a particular sequence of events that all the different players of the game have to go through in order to achieve some assigned mission objective, and that mission's success is the setup for something that happens in the show. So it's still the writers of the game and show deciding what happens, but since the players are acting out the scenario as written, it gives them the illusion that they're "causing" it to happen. At least, I hope that's all it is.
