Chris Chinn drops some knowledge about knowledge rolls, and as usual I like the cut of his jib
The bit I’m a little torn about is giving info that is deliberately wrong. Namely, in some games I feel like you should just tell the player that their PC believes a bogus piece of info and let them play out the consequences, but I know that for some games and some players, that sort of authorial perspective is anathema.
That said, I do like the idea that mere possession of a given skill means the PC has a base level of knowledge, and the roll is simply to know more than that. (That’s one of the few things I liked about GUMSHOE.)
(Aside: it seems like the good ideas born out of PbtA games is just never-ending. Definitely a milestone in RPG design.)
