Triggered by this question: https://rpg.stackexchange.com/questions/67626/how-if-at-all-do-gms-deal-with-secret-actions
It currently has no system tag, which is fine because it's not about a specific system. But it is about a specific category of systems where players keep information hidden from one another. Possibly because the assumption is that the player knows everything the character knows and vice-cersa.
This system is contrasted by other systems, which assume a strong split between player knowledge and character knowledge.
There seems to be some confusion, with people who are used to a system of the former not understanding how to work with the second system (giving us questions like How to do mystery based storytelling in Fate?)
There is also this question: Can I roll for a PC in secret? which is also without a system tag and where only the third answer actually says "depends on the game" (with the first two assuming a game of the first category)
This makes me feel we should have tags to explain the different styles of play, because they invite completely different answers. Except I can't for the life of me think up good names for them.
So I was wondering whether anyone agreed and had a good name for a tag to apply the question(s).
