I'm still amazed that time and time again how it is said something like the DM must shift focus on the whim of the players. But no one has ever said the players must shift focus to the whims of the DM. I wonder why not?
So you won't even say the DM gets to tell a story equal to the players?
Yes.
Though the above is the worst example ever. Though it's typical of the problem way of thinking. See this is an example of a bad DM. The DM has a path for the players....and for no reason, gives the player a choice. Well, whenever you give someone a choice.....they might pick the wrong path.
The "Fix" is easy: don't give the players a choice. There is only one door. The characters go through it and encounter that the DM has placed some interesting monsters, traps, and plot points.
Or....if you feel you must have two doors for some reason....just make both door lead to interesting things.
This is not the same as saying the players should never get to make any choices....just that a choice like this is a bad example.
Well, it's no "act", it's just true.
Well, this is good advice for dealing with average or good people that act in good faith. Though it's useless for bad or worse people.
It's complex. It would need lots of space to type out, and I would need to define each word so it could be understood.
