“Midway” is an out-of-print Avalon Hill board game that simulates the World War II battle of Midway, June 3-6, 1942 — the turning point in the Pacific.
The original, classic, “beer & pretzels” version of the game was released in 1964. (The 1992 Smithsonian “version” was a completely different game of the same name.) The game is easy to learn, but has a fair amount of depth, and is a decent recreation of the battle.
At one time, I was thinking about doing a browser-enabled version of it using PHP. I didn’t proceed to coding, but did a lot of data design work on it. The design is language agnostic. Feel free to use it.
