This game is a story that implores one to reflect about mortality, civilization, governance ethics, loss, space and what time is for us.
An absolutely fantastic game. I spend more time than I should have out of my nights and weekend playing this game.
It is a great game and has a touching immersive story. I had multiple moments where I almost took a step back from it, but feared too much, that I wouldn't dare return.
(got all achievements (mostly in order) except for the difficulty and violent ones (True Pacifist! (with the exception of Story forced on stuff)))
(sorry for the '(' and ')' "non [maths or programming or logic]" people (did this 'sorry' become worse than the actual sentence???))
Anyways, I particularly like Endings 2,3,4,11.4,12 and 5
2,3,4 are like watching seeds grow, 11.4 and 12 are nicely hidden
Tried to keep the following as spoiler free as possible regarding ending 5, though my following reflection about it contains highly vague - indirect references
5 for me is the most outstanding one, as it offers me the most food for thoughts, as it is not an ending I particularly would hope to see, but it seems the best between probability and goodness. It seems almost european in the way it handels things, though the path towards it is questionable.
Another thing to think about is how it deals with its scars. It may very well be highly unstable (as pointed out in the ending itself) but it may just as much be the one with the most long-term stability, if one can deal with it's scars. Reflecting on it, the easiest and most stable solution would be the precise one that it prevents.
At the same time it doesn't prevent "happy little accidents" like people working independently to increase the risk of something like ending 6 or the in story end.
Another thing is the risk of an ending 6 that it may create. Similarly would one need to prevent an undoing of ending 5 which would itself would need to be prevented, limiting quiet a lot more than what ending 5 itself may imply.
What I do believe however, is that what the last scene of said ending shows is unavoidable to deal with its scars. It is something I would love to go deeper into (like the need of binding referenda and initiatives), but that alone is too much.
After all this again, Thank you for creating and sharing this great interactive story with us. For you writing this story, I believe writing my thoughts and thanks is the least I can do. (it merely has a length of roughly 0.165% of the story)

Once again came back and made the most efficient endgame reuse, the whole timeline on one screen.
