I have a story idea what might be too big of an endeavor for me to take on. It will involve shrinking, fighting (between semi-autonomous things I haven't come up with a name for yet - sort of a "Mon" trope, but without the ones fighting having free will or personality of their own), and a neophyte-becomes-grand-master trope. It won't involve kids, though - must be 18+ to fight.
I'm writing down notes now, fleshing out the idea. I may take help from someone to make it a reality. At best, it might take a webcomic-style layout, but there's no way I'm going to animate anything. Mostly saying something so I feel guilty when I inevitably backburner the idea, so that hopefully I'll make some progress on it.
