What is the timeline for this game? I love all the vegetation (way more than in the first game), but this would have to be at least 10-20 years after the first game for there to even be a chance for there to be trees that large on top of the buildings. More realistically we're probably looking at 50+ years after the first game.
First off, you'd need enough dirt to accumulate up there for a seed to even take root. Then you'd need even more dirt to accumulate to the point where it would sustain a tree of any size. Vines and stuff make sense. Trees? Not so much.
I know this is a game and games don't need to pay any attention at all to anything resembling reality, however, it bugs me to no end as I'm constantly looking at these trees and wonder how in the world did they take root up there and grow to that size in such a relatively short amount of time?
That said the game looks great and the gameplay looks fun. I just wish it wasn't an open world game.
