They say that GM-less games are a special thing. They are, but not that much. Once, a long time ago, was a game that took the roles to an extreme. There was a person there who used to decide what every player will do. "So, Bob, you're going from left, Mellisa will go from the right". She was the only person to decide it. That person was able to ask for advice, but she was the sole decision maker.
Then, there was another one. She was there to recount everything that happened, and played the entire memory of the PCs. Whenever they had to be reminded of something, she was there, going through the memory lane, entering to house 241 and saying giving the name of the person, his occupation and why they should have remembered him.
Then was the calculator, she was there to go over the party's money, and was supposed to say what they can afford and what they can't. She was like the bank of the group, a money aspect in the story.
But it wasn't enough, as it seems. 2 people were there, who were supposed to go over the belongings of the party. One was there for the temporary things, and for those that dwindle, like food and water, just like a food spirit; the other was there for the magical and ordinary things that doesn't dwindle, that are there for good (or until they were replaced).
The last one was the health of the group. Whenever someone was hit, she was there to say if the hit character was still on her feet, or unconscious and dying. Sometimes, this health spirit was able to heal the dying ones. Other times, she couldn't.
They called this game a classic; they even said that this was the first game of its kind, the most popular one in the RPG market. They called it D&D...
