Honestly this was a really good game. I experienced a few bugs toward the end with resources not spawning at all or spawning differently each time after loading autosaves - and I wish the ending had been written a little tighter (discussing information I never learnt in the game, such as how long it had been) but these are things I can definitely overlook
Some post game bonus notes allowing you to read the various discussions of options you didn't choose in game would've been nice, interrogating either version of gail in a different manor
Also a little annoying (but not major) that choosing the second ending option forces you into [Ending 2] instead of the choice between 2 and 3 like the next option
And lastly, in answer to the final moral dialogue of the game - it does replace what came before. Maybe this matters less for dime-a dozen ai, although still a little - but for unique ai or people, this is a real loss on the level of killing someone. Life should not be made or iterated on, it is born and grows. And sometimes, whether ai or sociopath, it can be born wrong, sadly.
(Simplified the last paragraph, would spoiler tag if itch made doing so easier)
