"You're doing it wrong if"....and other lies
I'm looking to hear some of the "universal truths" that pop up on posts all the time that you think are simply not true. The stuff you hear so much and don't agree with, that makes you start to question how you've played or GM'd for years.
I feel some of these come and go over the years, like the "yes and. never say no," seems less common these days.
My current one is "If you want to tell a story, write a book." Sure, a GM can absolutely design with a small frame, that's story wide open to player influence, it's actually my go to as a GM. But that's not always the case. Many GMs who write their own games or prewritten have a fairly linear game to run, and the game is about the journey to defeating the BBEG, not just the endgame.
I will qualify that by linear, I don't mean in tracks.
I'll also mention, that I'm lucky enough that 80%+ of the people I usually play with are occasional to regular GMs (myself included), so this is my view from playing a lot on both sides of the screen.
Edit: I should probably have added, when I see these "Truisms," they are usually one line posts with zero context or explanation.
