The largest issue is still the deserts. People can move. Climates can not. At least not too far from their origin.
Climates are based on lots of things, and if the poles changed like you said possibly happened earlier, then they can change absolutely. Pars of Antarctica used to be a tropical forest, for example. Change the Ecuador, you change deserts to forests and forests to deserts. Hawaii was just a ball of solidified lava, now its a tropical holiday destination. Climates are dynamic, just like everything in the world.
Oh, also, I am the one that did the comparison.
Sorry, I didn't check. Really nice work on that by the way.
Didn't see that picture of the Chrysler building though, cool stuff. Still, I took this question to the devs, and I got a response. We are both wrong, although we were right about some things. It seems Muse is purposely throwing all these different locations in to confuse us, because they still haven't claimed one region to be the map. The Alliance map is the only known place left in the world that can sustain life, although people haven't traveled too far so even that isn't for certain. The map has almost no specific correlation to any part of the world, reason being that there was so much war in literally every part of the world everything changed. Seas were made and deserts of both ice and sand swept the globe. Basically, nothing is the same, at least in the known world. A point that was also made was that there was no Berlin in this world, removing the possibility of Labyrinth ever being that. Though it was a great city of some population, and possibly the last stand for that people. It is also mentioned that there were two world powers that started the war, then there were potentially more who joined in. Nothing was mentioned about alliances dragging people in like in WW1, just that two world powers started to have a little fight. Another note, the Vastness (area where the Mercantile Guild come from) is thought to be a site of detonation for one of the many doomsday devices (but no one knows for sure). So that's pretty cool.
So, with that in mind, we can't zoom in on any one piece of the globe, but with the little details we have, we can narrow it down to a few places. America being a solid possibility, especially the eastern seaboard seeing as that is the most likely place to find the Gothic-like architecture found in Labyrinth, not to mention the Atlantic being near. It definantly can't be anywhere that doesn't speak English, Portuguese, Spanish, Afrikaans, Albanian, German, Czech, Hawaiian, Latin, Italian, and a lot of others. Basically anywhere Europe touched, except France, Iceland, India, the like. That being said, I'm pretty sure we can forget about the Midwest of the entirety of North America, because there is nothing out here and really no incentive to ever put anything here. Grass is terrible.
Who knows what happened to the poles, the continents and pretty much everything. It could all be different, after all, we only know of one absolute doomsday device in our timeline. That would be the Nuclear Bomb, who knows what a crazed pre-nuclear society came up with to blow up the world.
