1913, the British novelist H. G. Wells took his own stab at the genre, publishing Little Wars: A Game for Boys from Twelve Years of Age to One Hundred and Fifty and for That More Intelligent Sort of Girl Who Likes Boys’ Games and Books. The text amounted to Kriegsspiel for Kiddies: a short, simple, accessible set of rules. Wells did away with complicated boards, encouraging play on a kitchen table or bedroom floor. And he ditched the counters and markers that represented military units: Little Wars required only a child’s own collection of tin soldiers.
