There's a massive difference between reading the rulebook and playing the game.

Reading the rulebook gives you the from-the-balcony, passive intellectual understanding.

At every step, if your mind wanders, or you miss a key implication, nothing will happen.

There's no stakes in the moment.

Playing the game gives you the visceral, in-the-arena, active experiential understanding.

At every step, if your mind wanders, or you have a crucial misjudgement, you're knocked out of the game.

Only the latter can calibrate your intuition and help you feel the game's logic in your bones.
