There are still people who believe this even though poker doesn't have rules for bluffing.
I could write a thing but Natalie already did it.
That thing Natalie wrote should be required reading for every single person whose ever even pretended to be a game designer ever.
It is so good and so smart and so right and I have to link to it like twice a month because even people who are professional full-time game designers think stuff like "Well if there's 8 pages of rules about cars and only one page about kissing it's a game about cars".
It's so sad.
If those System Matters essays spawned a whole website and then a whole forum and then a whole game design community then this essay deserves a whole continent to itself.
That is all.
