I love WW2 war histories. I don't like studying the politics and ideologies since I've never been a fond of those, but I love the wars, technology, and generals.
If I were to write a WW2 story, it'll probably be a historical fiction where you play as a good German panzergrenadier during Operation Market Garden. No extermination of Jews or concentration camps or Waffen SS going on a murdering spree since I'm more about tales of heroism and survival, not mass murders.
