Heartwarming / Total War: Warhammer III

• The main campaigns for Kislev and Cathay have them making expeditions to invade the Chaos Wastes. Our heroes are willing to go into hell itself for the sake of protecting their lands.
• If you manage as one of the Kislev factions to hold control of Praag, Kislev, and Erengrad simultaneously for ten turns, you'll get a special quest. What is it? Rescue Tzar Boris, who is still alive in this continuity! It's an especially poignant moment for both Katarin (Boris is her father) and Kostaltyn (Boris revived the Cult of Ursun and created the Grand Orthodoxy). It is also a very uplifting moment for the whole of Kislev, as their greatest Tzar is literally returned to them in their darkest moment.
  • If you succeed in saving him, he willingly chooses to Abdicate the Throne, because he's proud of who his daughter has become and doesn't wish to get in her way.
  • Saving Boris permanently unlocks him as a playable Legendary Lord from the get-go, complete with a special intro — in a game where you play as Katarin or Kostaltyn, he's trapped in a glacier by the Gods of Chaos, necessitating his rescue. Start as Boris, though, and he breaks out of the glacier through his own will! Why? His people and his god need him.
• The Cathayan Royal Family is rife with Sibling Rivalry and rampant Parental Favoritism. There have been multiple full-blown Civil Wars between the Dragon Children, one of which lasted for four hundred years, and to say that all the siblings are still suspicious of each other would be a massive understatement. So what does this dysfunctional, maladjusted family do when their little sister Shen-Zoo goes missing? Do they start pointing fingers and laying blame? No. They prepare to charge into Hell itself to find her whereabouts. Can you say Aww Look They Really Do Love Each Other?
• A minor one: every single faction leader will follow through on their promise, and give the Advisor his one drop of blood - even the Daemons, who you'd normally expect to screw him over at the last minute. Sure, it probably helps that it's such a minor desire... but even so, that a deal made is a deal kept for every faction leader is kind of touching.
• At the end of Kislev's campaign, it turns out that Ursun has already expired from his wounds, which breaks the will of whichever Legendary Lord you played as. But as all seems lost, Ursun, moved by the devotion shown by his flock, comes back to life to save his people from their ongoing Eternal Winter.
  • At the end of the Cathay campaign, the same thing happens; the children of the Dragon Emperor arrive too late to save Ursun but discover through channeling Shyish that Ursun's spirit is still on the mortal plane and they can summon him one last time using a spell. The Bear God uses his last moments to show the dragon-children where they can find their beloved sister Shen-Zoo, even though they are not his people and there is nothing he can gain in doing so. Why? Because God Is Good. When Ursun then fades from the world forever, the dragon-children vow to honour his last kindness.
• In the Heartwarming page for the first game it was noted that Vlad and Isabella von Carstein's Unholy Matrimony was oddly touching. As of Immortal Empires this is all the more so, as their faction, Sylvania, is now the only faction with more than one legendary lord option, with the one you don't pick becoming a legendary hero. When every other legendary lord headed off on their own the undead's top power couple refused to be separated. It also ensures nothing that happens in the game, no twisted web of alliances or political dispute, high elven intrigue, Tzeentchian manipulation, or Slaaneshi temptation, can turn the two against each other.
• The new ability to give settlements to other factions allows you to finally be liberators for your allies. While in the past when other factions lost territory all you could do was conquer it yourself or raze the settlement and hope the other faction resettle it now you can take the territory and return it to the rightful owners. This is especially touching when done between longtime allies in lore, like Imperials with either Kislev or the Dwarfs.
• In the Immortal Empires trailer, Karl Franz proposing an alliance of Order against the onslaught of Chaos and Destruction. And when Teclis and Thorgrim nearly ruin it with an Elves Versus Dwarves diplomatic fumble, Franz is the one who gets them all to look past their own selfish interests and fight together for the fate of their world, over shots of just that: the Wood Elves and Lizardmen fighting side by side, Tyrion and Grombrindal as Back-to-Back Badasses, Balthasar Gelt and Zhao Ming unleashing their combined artillery on a Skaven horde, and finally Katarin and Kislev facing down Archaon and the tide of Chaos with Franz himself and the Empire beside them.
  • Even the Tomb Kings are counted amongst the Order factions, as they take on the Vampire Coast, and the Greenskins, showing that even being undead does not automatically mean being "evil".
• This game, particularly Immortal Empires, brings the series recurring element of A World Half Full to its logical conclusion: alliances can be forged, old enmities can be overcome, and most importantly, Chaos can be definitively defeated. For the first time in a Warhammer setting, the world can truly become a better place.
