“Some games are so rule-laden that their epic tomes of instructions could rival a fantasy novel. For example, topping our list of board and card games with the longest rules is Magic: The Gathering. This card game has a rulebook with a whopping 100,000+ words. That’s more words than in the entire The Hobbit novel, which is 95,000+ words, for the record.”
