I've explained this several times lately and I don't like repetition so you're getting a novel explanation:
You know how people always say you should do what you love doing to make a living? I already do what I love doing, so to do what I love doing for a living, I need to make a living of what I'm doing now.
Makes sense so far?
Now let me clarify that, by far, money was not my first concern. In fact, it only concerns me indirectly, more on that later.
I had to think of an 80-hour project for school and while most do some sort of simple, not-so-original research that has probably been done a few hundred times, I wanted something with a real result that wasn't there yet before, be that new knowledge, a new theory or a board game.
Since I'm in high school, it might be a bit early for me to discover actual new knowledge through research, since in amy discipline, there are many researchers who know so much more and it's just out of my league. I then thought: maybe put a product on the market. I have a novel product in my head and I've been unable to find the time to really make work of it. Sadly I don't have business administration classes because I couldn't take those with my other classes.
Then I hesitated between writing a book or creating a board game. I wasn't even sure whether writing a book was allowed since it needs some sort of research-aspect I believe and 80 hours doesn't seem close to enough anyway so I went with the board game. The research aspect will be in an interesting take on chance calculation, which I haven't had any classes in.
Then I made lots of progress, now I've got a solid game in my head and I'm working on getting all of it on paper, which is extra time-consuming since I need to write down the whole process for school as well.
Now I'm arriving at a point where I can start deciding what the units look like and in this case it's mostly a money question.
So that is why I am, only now, looking into the money aspect: it's relevant to development for me, not the other way around.
Why do I seem to care about money so much?
It has a lot to do with securing my future. There's enough people who don't want a job, want to start for themselves, produce stuff, invent stuff, whatever.
I'm no fool; most of them fail and can only pray they can get a job.
I want this, but before I can really commit to not getting a job, I need to know I can pull it off. I need to know I can make a living my way, so I no longer have to keep all those options open.
Maybe I don't need to, but it seems sensible to test my skill, perseverance and success in the 'career' I'm following in my spare time before really throwing myself in.
So it is not my first concern, but why is how much money I'm getting from it something I'm looking into?
Because the certainty with which I turn down jobs so I can continue on this path depends on it. This path is important to me.
Does that answer your question?
I also don't recall saying I'm surrounded by a huge group of people who would be more than happy to playtest my game, but it isn't ready for playtesting yet, although I want to be able to start 'pre-alpha' tests fairly soon.
