Tom Chick - "When you’re really good at a strategy game — a boardgame, a card game, Civilization, chess — there’s a whole other kind of pacing than when you’re learning it, or just casually letting it unfold, or playing it as one of a half dozen other strategy games currently rattling around in your brain. The dilettante considers each move because he doesn’t know the game well enough to hurtle through it. When you master a game, your brain works as if it has muscle memory. In a given amount of time, someone who knows a game well can play twice as many games as someone who doesn’t. Maybe three times as many."
