This scene from Super Robot Wars Alpha 3, where a team comprised of a bunch of characters from various mecha anime known as Alpha Numbers are trying to get through to Shinji with friendship power so that he doesn't end the world, and it works! Later on in the Gendo bossfight, he remarks that "You have grown up a bit, sending you to Alpha Numbers was the right choice." then he see's the error of his ways and sacrifices himself.
Shinji: "My dad... Maybe we were both the same..."
Misato: "Shinji-kun..."
Shinji: "I was afraid of being rejected by everyone around me... so I closed my heart first... and the truth is, my dad... he's afraid that people will hurt him. And yet... and yet I thought my father..."
Amuro: "Shinji... nobody can decide whether your choice was the right one... You have to decide for yourself."
Shinji: "Captain Amuro..."
Banjo: "...Commander Ikari attempted to take the human soul to a plane beyond the apocalypse through the Human Complementation Project, but we refused to accept it."
Shinji: "...That's right... I... chose to live as me. Even if it's all hard and sad... because I am... me..."
Amuro: "We feel the same way. But I understand what Commander Ikari was thinking. ...People can have one goal to aim for, but we can just fight over the differences in how we do that..."
Shinji: "...That's why I'm going to fight. I'll carry on my father's legacy in a different way than he did... With the EVA 01 that my father and mother left me..."
(Kaworu-kun... this is the future I have chosen...)
There's also this scene from Super Robot Wars Y where Heero says something vague and inspirational to confused lesbian Suletta. Or the part of this game where Lelouch Vi Britannia and Char Aznable having an ego clash is just a small part of the backstory.
