Total War/Awesome


 * You are fully capable of pulling these off with your armies. Mostly denoted when the end-of-battle statistics pop up with the words "HEROIC VICTORY" splayed across the top.
 * Very possible to capture a castle and defend it the very next turn against an army two or three times the size of your defenders simply through smart placement and movement of defending units. It's also extremely satisfying.
 * On top of all that, starting from Rome: Total War, your generals' exploits will become the stuff of legends in-universe. Your general will gain a reputation (and requisite stat-boosting trait) of Five Star Badass, and for the rest of your campaign there will be a monument on the campaign map dedicated to your victory.
 * For Shogun 2: "MY LORD! A GLORIOUS VICTORY WILL SOON BE YOURS!"
 * Killing another faction's king/leader on the battlefield is certainly glorious. "The enemy king has been slaughtered!" or "The enemy leader has been killed!"
 * In Rome: Total War, capturing the city of Rome itself qualifies.
