I post 4 paths: North, south, east, west. Player 1 is in the middle.

Player 1 picks a path

Player 2 posts an event/scenario and asks what the next player will do

Player 3 decides whether to take an action or pick a path

Example: 

Player 1: Picks east

Player 2: A cat appears. Do you interact, continue on, take right path or left path?

Player 3: Interact!

Player 4: The cat rubs on you and you pet it for a while, then it leaves. You continue and come to a split in the road. Do you take the left or the right?

I hope this makes sense. If not, please ask!

You awake to find yourself lying in the middle of a crossroads. Standing up, you look around. At the entrance to each road, there is a sign that reads "North", "South", "East" and "West".

Which path do you choose?

Picks west because west is best!

A  donkey is standing by the way, looking at you expectantly. Do you interact, continue on, take the left path or the right path?

Interact, of course. It's physically impossible to pass up a donkey!

The donkey hears its owner calling, so turns and trots off.

You continue on. There's a split in the road. Do you take the left or the right?

Left

It starts to rain.

Do you take shelter under some trees or continue on?

Continue on. Rain is fun :D

Rain has stopped, do you cross the river or follow the banks?
