Earlier in life, I was quite a wargame fan: I had dozens of games by Avalon Hill, and even experimented a bit with miniature wargaming. I still have a few interesting old rulebooks for games, like Fletcher Pratt’s Naval Wargame. I recall reading back then that H.G. Wells had published a set of rules called Little Wars which I just discovered is available via (you guessed it) Project Gutenberg. Neat!
