Friend, I know that Bionicle is special to you. It contains a huge amount of emotional significance for you. It does for many of us on this discussion board. But you can't build your entire life around it. What you've said has crossed the line from fandom to extremely toxic thinking. This is why people commit suicide - this is the early stages of it.
You badly need something in your life besides Bionicle. Bionicle is NOT everything. Yes, it has a story, and that story has meaning. The meaning (for me, at least) has to do with overcoming evil, in spite of difficulties and obstacles and personal shortcomings. Collecting toys and focusing on that as your life's purpose doesn't overcome any sort of evil. We need people to work on overcoming evil in real life, and that is hard work. It's ugly, it's not pretty, but we should take a lesson and do it. And evil is everywhere, in every profession, in many people's hearts. Doing it in real life takes courage and it takes skill beyond what Bionicle can show us. Because Bionicle is a kid's toyline. The message is simplified for kids to understand. We need to move beyond it and learn how to fight evil in reality. That is the best way to honor Bionicle's legacy.
Collecting plastic toys, on the other hand, and sitting around and waiting and moping, does not have any meaning. It's too easy. You just earn the money and hand it over. You could have spent that money on other things, things that might have improved your life and maybe even your friend group. Instead, you are sitting around like a spoiled child demanding that Lego give you what you want. You are 25 years old. You have a life to live. Instead of actually living your life, you are making an addiction to a fantasy world of the life that you want to live that you think that Lego can somehow give you. Lego is not going to live your life for you. Lego doesn't even care about your life. Why? They canceled Bionicle, for one thing. Start there.
If you want Bionicle back, you're going to have to work for it. Nobody else cares anymore. You're going to have to do the work to design the sets and take the concept art to Billund for the story. You'll have to convince other people to join you, that your product idea is viable, that you can sell it to a bunch of little kids who don't care about Bionicle at all. And you won't even be able to do that if you don't have meaning and purpose in your life beyond what you don't actually have. Chester Bennington sold his pain to us for years - all those people who didn't know what it was and some who didn't care, and we all know what happened to him. Please don't live your life like him. Please.
Right now, your life is being defined by an absence: the absence of Bionicle. Your life is being defined by your pain. You cannot live a life defined by pain. You need to live a life defined by a meaning, a purpose based on something that actually exists. Bionicle doesn't exist anymore. It's gone. At the very least, it doesn't exist right now. And your purpose must be defined by your present, NOT your past - what exists in the here and now.
Example: Let's say I fail out of university and transfer to a new school. I had a purpose in that university, but it failed. So I don't go back to that purpose. Instead, I build a new purpose in the new school.
In the analogy, let's say that your purpose was something when Bionicle was running. Bionicle is the university in the analogy. Its purpose failed. So you need to move on and construct a new purpose for yourself. When you construct a new purpose for yourself, you're not losing Bionicle. You don't have to sell off all of your sets or stop talking about or stop posting here. Instead, you are building a healthy relationship to it. You are saying "this is a part of my life, but it is not the whole thing. I have a purpose and that is this." Maybe you can take the overcoming evil example above. Maybe you can say "my purpose in life is overcoming evil, therefore I support this toyline that promotes that message." That's how I think about Bionicle. Am I suddenly less of a fan in your eyes?
What about the people who are here because they like building things and use Bionicle as test practice for modelling and design? Are they suddenly less human because they don't "support the cause" as much as you do?
It's less about why Bionicle is special, and more about the meaning that Bionicle has. As another discussion from long ago once said, a rabbit does not have inherent meaning beyond its context and you know, eating grass. What purpose does Bionicle have for you? What is the meaning of Bionicle?
Now step back. How can that meaning be expanded and applied to your life? Not in support of Bionicle, but in general. For example, since I believe that Bionicle's purpose is overcoming evil, I spend a lot of time writing. I find that writing allows for messages to be spread that stop the spread of evil. (Suicide being one of those examples, which is why I wrote all of this.)
Your purpose is more than paying Lego for new Bionicle sets. If that's what you think your life's purpose is, you're missing out on a lot of life. Please do not commit suicide over this. The fact that Bionicle is probably not coming back is not worth ending your life over.
Nor is the sorry state of constraction in the 2010s worth ending one's life over, in case anyone was wondering about that. It should not be wrapped up in one's life purpose. Yes, it isn't great - we all know the usefulness of constraction in building - but yeah. Stay safe out there folks.
