I've never understood the wargamer guilt argument or the attitude that "you must love war" to play it.
A huge chunk of popular entertainment is based on conflict of some type. Whether it's football, or Mortal Kombat video games, there's some level of conflict at the root of a lot of entertainment.
The fact that I choose to my entertainment based on my interest in historical settings isn't called into question when I read historical fiction like the Sharpe's Rifles series or the Aubrey Maturin series! If I read a biography of Rommel, it doesn't make me a Nazi sympathizer. Why would my choice of interactive entertainment somehow create a new line of logic that would lead to such ridiculous false assumption?
Guilt? Absolutely not. Empathy and Compassion for the position both soldiers, military and civilian leaders must have faced? Absolutely.
I can't imagine a higher stakes leadership challenge than wartime leadership. That said, I also can't imagine studying history that's 1 year old, let alone 75 years old, without some kind of interactive component to experiment for myself. Video games and board games make excellent lab settings for this despite their obvious shortcomings.
