It's interesting, it's certainly very sad to watch Simon and Catherine argue as the lights go out but as I wrote in my old post linked above, I was totally at peace with it and in agreement with Catherine. I just wanted Simon to shut the hell up and spend his final moments being happy for Simon 4.0 who he'd essentially just granted immortality in paradise rather than whining about his own fate, which surely, surely he should have seen coming?
He needn't despair anyway, he'll be one with the WAU soon enough. You guys did leave the WAU alone, right? You didn't snuff out the future of life on Earth like bludgeoning the first fish to crawl onto land, surely?
I couldn't help but imagine the simulation hitting space rocks or crashing on a planet and it gave me anxiety every time. It's kinda funny writing it but it's still a pitiful and depressing state of affairs, even if they don't know it, so... Yeah, maybe you're right, maybe it would be paradise. What an amazing ending whew.
I've played through it twice so I'm sure I did it both ways but I remember thinking at least the WAU could eventually adapt and evolve into something resembling real life. It's been a while though, so I don't remember the in-world limitations to that possibility!
