Yeah I should do that, I started to do that actually, but as you just said, OS, as it is now, and it will still be for probably an awfullylong time, is constantly stricken with restatements, retractions and modifications.
For exemple, some calculum made me decide that Meiya was better off being 9 rather than 12 ( as I anounced she was supposed to be by 2054 ) because that would make her be 26 in 2071 ( which is more convenient to me ). You can imagine the nightmare of keeping any kind of background page updated with something that keeps changing...
Anyway, if you put all the tiny details aside, the thing as a whole is not ground breaking if you take originality into account, s I can resume with:
Mankind goes to space, clonizes mars, independance war with mars, aliens arrive, war, other aliens arrive, war, etc.
And yeah, it's an original stuff, not drawn out from a manga ( tho there's obvious inspirations from many anime series, but also movies, books, hell, there's even inspiration from some of my mum's cooking tools for some designs ).
