Planescape: Torment/Heartwarming


 * Playing as a good character nets you a lot of these. Especially the "best" ending.
 * Despite all the horribles things you've done to them and can still do, you and members of your party can have a pretty good happy ending. It's easily missed, but as you travel in the Fortress of Regrets you can gain the ability to resurrect dead... And cause enough mayhem to get the Transcendent One off your back long enough to raise each and every member of your party. Feels pretty good after powerlessly watching them die. You also get a nice chat with each one and they reassert their will to help you. This troper always choose fighting over talking the boss to death because of this last discussion with your friends, at least last discussion "as yourself". That way they don't wake up after their violent death to see you have changed. Bonus Points: with that last chat? You can FIX Dak'khon's mind and making him whole and focused again, and give Vhailor the biggest injustice to punish. Both of them become because of that nigh-unstoppable owerpowered killing machines, always a nice touch before the Final Boss.
 * And after the Transcendent One is dealt with: your farewells. Even better if you had the opportunity to talk to them BEFORE the fight: at least you had the chance to fight alongside each other one last time. You can say goodbye, thank them, apologize for what you've done... And each of them shows his appreciation: "it's been a pleasure" from Morte, an silent declaration of love from Annah, the promise that Grace will find you again, settling your debt with Dak'khon... Even VHAILOR says something "nice", along the lines of "you're going in hell, but that's no meaningless punishment: use it to become better." Ignus, of all people, begs your forgiveness at having betrayed his "master's" teaching... and you apologise for your betrayal and then send him to the Elemental Plane of Fire, probably the one place he'll ever be happy and at peace without being a danger to anyone else.
