I really like every war leading up to "The Great War". I feel that up to that point generals and commanders had to manage their troops a lot more. Battles were slower, cavalry was the hammer that all armies needed, and artillery was important, but not as necessary. I feel that after the Franco-Prussian War, war degraded to Trench Warfare and the absence of charges, cavalry, and "better micro" by commanders, and by no means am I saying that modern war doesn't require tactics, but a battle can change in an instant from an airstrike, artillery barrage, tanks, or any of the modern implements of war.
