It turns out that there are a lot of different types of “quantum” at play in RPGs. I think it might be good for conversation to have a taxonomy of them. So here goes.
Our situation is that last session it became clear that in the next session the group is planning to move through a forest using one of the two well known paths (A and B), but they have not yet decided which. This forest is known for having a particularly ferocious Ogre roaming it. What are possible approaches to decide if the group encounters it as they move through the forest?
1: The classic locally deterministic quantum: Once the players commit to a path, the Ogre appears on that path.
2: The local evenly random quantum: Once the players commit to the path, the GM flip a coin to see if the Ogre is on that path.
3: The global evenly random quantum: Once the players commit to the path, the GM flip a coin to see which path the Ogre is currently guarding.
4: The local uneven random quantum: Once the players commit to the path, the GM rolls D20. If the players chose path A the Ogre is there on a 5 or lower, if they chose path B the ogre is there on a 15 or lower.
5: The global uneven random quantum: Once the players commit to the path, the GM rolls D20. If the result is 5 or lower, the ogre is on path A, otherwise it is on path B.
6: The oversaturated local random quantum: Once the players commit to the path, the GM rolls D20. If they chose path A the Ogre is on the path on a 15 or lower. If they chose path B the ogre is on the path on a 10 or lower.
7: The weirdly entangled local quantum: If a character is declared to “be alert” while moving through the forest, the player rolls a D20. On a 6 or higher the Ogre is on the path. If no one makes such a declaration it is not on the path.
8: The ultra local random quantum: While the party is traveling through the forest, roll D6 every hour. On a 1 they encounter the ogre.
9: The even random stocking: Before the session the GM flip a coin to determine which path the Ogre is on.
10: The uneven random stocking: Before the session the GM roll D20. On a 5 or less the Ogre is on path A, otherwise it is on path B.
11: The deterministic stocking: Before the session the GM decides where the ogre is.
and as a bonus
12: The anticlimax: There is no Ogre to encounter, as the last party passing through already has slain it, and its remains have been consumed by forest beings.
Which of these do you find acceptable? Which are unacceptable? Why?
I have quite a few thoughts about this myself, but I guess this post is long enough as is.
