Calling something a game mechanic that has no mechanical game effect either means you're trying to sound smart, or you don't know what words mean.
"Now choose an eye color." is not a game mechanic. It's flavor. And not even good flavor. It doesn't fuel story, even. It's an affectation.
"Tell me why you want to kill the great wyvern, Tibernus the Third." is also not a game mechanic, but it is a good anchor into the story, assuming of course that killing wyverns is the point of the game.
Shut up with your pontificating about mechanics, Regina, when you don't know what mechanics are.
You left twitter to get away from this kind of noise.
