Ah, yes, my fellow AC obsessive, of course as soon as I started talking to final boss debater, that's where my brain went. I mean, yeah, you think it about for like a minute and it's stupid but, hey, that's the beauty of video game story-telling- it feels cool in the moment.I liked the Forgotten city, except for the shooting bits which I have no idea why they are in there other then "Well, we programmed a bow so we gotta put some zombies in there".
I felt the big twist of the cannon ending killed my immersion a bit because while it tries so hard to over explain everything, it invoked a particularly tired trope that I felt didn't need to be used(I'm fine with Ancient Aliens in the Assassin's Creed Series but that's got it's whole sci-fi conspiracy vibe thing baked into it. I don't feel it benefits this story ) and also opened up a bunch of new questions that don't get addressedCharon bringing people back from the dead, even 2000 years later because......reasons. It's kind of a shame because I was really into the whole thing until that point.
If the gameplay wasn't so Skyrim blech I might have tried some save spam / replay thing to see all the endings but I'm good with the one. It was perfect to play for one day.
