Thanks for the short explanation but I still wish for more comprehensive one :-)
Something like Mark's would take almost a year to do.

Yes and no :-)
One could make a working copy (as Mark used to make) with new missions added every few days. That way people like me can use it right from the start playing in the same pace.
I've found japanese walkthrough with some story notes if anyone english speaking is interested here is google-translated link:
Also LetsPlay diary could be very useful for game understanding (it is not far in story now but should progress):
Translating in detail would take more time that I'd rather spend actually playing the game. If down the line you have specific questions and I happen to be on the board I'll answer those.
