The Same page tool by Bankuei is a valuable tool to discuss play before play :
I want to add one question to it :
Do the GM and players get to say “what’s true” (he falls in love with you ; 1D6 level 3 orcs) or only “what’s perceptible” (“he can’t help looking at you smiling as in a reverie” ; “the players encounter a strange looking creature on the side of the road”) ?
The mechanics always “tell it straight”
The GM always “tells it straight”
Anybody can “tell it straight” for ease of play
When they are not “telling it straight”, but hinting at the truth, they explicitly signal it
Nobody never “tells it straight”
(multiple answers are possible)
I probably got some wrong, but you get the idea. Can you inform this from your viewpoint ?
