Notice in MTW theres actually some combat, when the enemy front and yours combat it lasts for several moments and swings back and forth, In RTW the combat lasts a few seconds before somebody (usually the enemy) Breaks and runs..By the time you could get a horse flank-attack they arleady ran.

Im thinkin you could change this by turning unit attack down by 3-5? or maybe turning the defense up 3-5?

Is there a potential mod in this? Battles in RTW go fast, and to fast to enjoy the graphics
