Locations

Areas

 * 2 - Guadalajara Philadelphia Tokyo Berlin Montevideo Osasco Toronto Gothenburgall serve as an inspiraton to a location the player gets to first. It's a massive city which we see at sunset/midnight during the events of the game.
 * 46 - Illinois and Kansas both serve for the short time we spend in Alcobia's farm
 * 286 - Utah, Gobi Desert (and Antofagasta with a dried out beach/port) all blend in to create barren steppe land with cliffs in occasional places. The tribe is met here, next to a river in the cliffs.
 * 544 - With the bleak yet densely creepy atmosphere of Far Cry/Crysis mixed with Stalker inNew Jersey Palisades and flooded areas everywhere, the players must traverse through the acid rain forests not far from the likes of Louisiana's landscape (caused by global warming, it looks like it's on the way of Waterworld)

Names

 * The areas are numbered in no particular order, they're split up by this formula - once the area has reached the population of 100,000,000 inhabitants, it gets bordered from the next area and given a number.
 * It is illegal to cross the borders of one area to other - doing so would disturb the amount of people in a particular area if they all emigrated to another one. An useful trivia is the fact if there's a large population growth and it reaches 200 million inhabitants, then the area will be split into 2 different ones and both would be named the same number but with a connotation like 5A and 5B, but this is avoided in practice since there's plenty of numbers available and would defeat the purpose - having a particular set of a number and a letter would give the inhabitants SOME sort of identity.
 * It doesn't matter how small or big the area is, all it requires is to have 100 million inhabitants in one, so in deserts it's an obviously hugely sized area as opposed to metropolitan areas.
