These are role-playing games played without a formal GM using the Mythic GM Emulator tools.
Effectively, we enage in a stream of consciousness style of play, developing both the setting and the specific adventure. Some are one-offs, others may have more than one session.
From a review on RPG Net:
“Mythic Game Master Emulator is designed to be a kind of pen-and-paper artificial intelligence, using simple logical rules to answer yes/no questions. So, it acts like a GM itself. That means a GM can use it, and generate an adventure in a flash. You can even play without a GM and have players ask questions to the system directly. The entire system hinges on using simple LOGIC and INTERPRETATION to move everything along, with the 3 main charts throwing randomness into it and several mechanics that generates unexpected plot twists.
You will use the following tools to create your adventures:
- Scenes = Just like the movies, a scene is staged. You create adventures with numerous scenes. A scene is what you expect to happen, resolve any conflicts, and move on to the next scene.
- LOGIC = You use this to find out what will happen next based on what has already occurred in the adventure. What is most logical is what is expected to happen…but fate is fickle.
- Improvisation = Player(s) ask questions and the answers will propel the adventure forward.
- FATE CHART = After you have formed a yes/no question then the player(s) figure out the ODDS (“Impossible” all the way up to “Has to be”) , cross-reference the CHAOS FACTOR, roll the dice and find out the answer (The results are either “yes”, “no”, “exceptionally yes”, or “exceptionally no”.)
- CHAOS FACTOR = This provides a shift to every question towards the “yes” outcome. This has the effect of “mixing things up.” The CHAOS FACTOR is tracked throughout the adventure to represent how out of control situations are becoming.
- Event Focus & Event Meaning = There are times (many times) when designing scenes and using the FATE CHART that you will have a random event pop up. These events could be good or bad for player characters or the adventure depending on the Event Focus Table and the Event Meaning Tables and your LOGICAL INTEPRETATION of those meanings.
- INTERPRETATION = Many times you will have to decipher the answers you get from the FATE CHART, Event Focus, & Event Meaning to fit LOGICALLY into the adventure.
Basically you ask a yes/no question. The LOGIC of that question is then applied to the FATE CHART, which gives a percentage probability of a “yes” answer. Roll 1D100 (or 2D10). The results are one of four answers. The player(s) then INTERPRET the result to fit LOGICALLY into the adventure. Traditionally you ask the GM questions such as: “do I see anyone in the room,” “do I hear anything behind the door,” “is there a town up ahead,” “does that crowd of orcs look angry.” Anything you would ask a GM you can ask the FATE CHART as long as it is in the form of a yes/no question (Mythic: Variations book provides mechanics for complex questions). Everything branches off from there. It is no different from playing a game with a living breathing GM. As a player, you have thoughts and expectations of what the adventure is about, what is going to happen next, what is in that room, who the bad guy really is, etc. Mythic Game Master Emulator just reverse engineers this process; instead of your expectations trying to guess what the GM is thinking, your expectations shape the games reality. You assumptions might be wrong, just like in a standard game.”
We suppliment the Mythic rules with Brewers Dictionary of Phrase and Fable to generate ‘ink-blot’ random inspirations (by rolling 3d10 we get a d1000 which almost exactly corresponds to the numnber of pages in my edition. Then we select an item off the page with whatever dice fit the number of entries.) For specific role-playing tasks we use Chaosium’s Basic Role Playing (BRP).
