What is the defining wargame to you personally?
In other words, what game embodies everything that a wargame should be, i.e. what is the quintessential wargame?
For example, someone once asked me a similar question about rock music. My answer was the Rolling Stones' Satisfaction. It's not my favorite song (although it is quite good), I'm not sure I would even call it the best rock song. But, to me, it embodies everything that a Rock song should be. If someone was completely ignorant of Rock music it is the song that I would play for them to show them what Rock music is.
Right band wrong song (Satisfaction is great!). Gimme Shelter, best song ever. An oldie that sounds great every time I hear it!

Wargame, I'm not joking this is me real opinion-Case Blue!
