I had anticipated that problem and solved it accordingly. Going in the game's order, I had unlock every ending according to chapter and then decided whether to go through Kurisu's or Mayuri's ending, and no matter what, I'd end up with the True End. Perhaps, that's not how it should be played. I feel I doomed myself to feel that much worse in the end. I've experience every single shred of Okabe's pride. The entire visual novel I'm just wrecking everyone's good time with my willy nilly time traveling microwave. I cannot imagine anything worse, other than the movies successful attempt at spreading the plague of depressing themes.
From my perspective, I've only played the VN. I've got so much content so explore, but I'm not sure if I could push myself to do that. Maybe its a good thing to do that? Its odd enough that I'd get this attached in the first place. Perhaps that is why I am hesitant to accept newer additions for the sake of preserving the character for what he is. I should give every single piece of content a try. How much can you fuck up his character? You cannot fuck up The Great Hououin Kyouma! You'd have to make him super tsundere to muck up his character!
Both endings are pretty much alike. There is the theme of sacrifice. Kurisu makes a bold step even though she doesn't actually want to die. She had explained how she doesn't die from her perspective, and in that, she would survive. As if she was given the power of Reading Steiner. She goes on to say because Okabe perceives her death, then she dies in this worldline. However, in any other worldline, she is alive. It didn't quite understand it until I thought about it, and even then it was theoretical mumble.
"Isn't that just from your subjectivity, Okabe? The me your brain recognizes will die when you go to the β World Line, right? So, basically, between the choices 'a world line where I die' and 'a world line where I don't die', your subjectivity chooses the former. However, the world your brain recognizes and the world my brain recognizes could possibly be two different things, couldn't they?"
