Metro City Limits

The world of Metro City is constructed to have finite limits that are proportional to the number of ihnabitants. As the population grows, so does the world-- but the city’s residents are still confined to the world’s borders. Over the course of the game new areas will periodically crop up, and the borders of the explorable world will expand accordingly.

Here's what's known about the world so far.

Where is Metro City?
Limbo. It's not really a world in its own right, more like a holding space for whoever's been put there.

What's keeping everyone here?
It's unclear right now. But what is clear is that you're stuck within the confines of the city, which comes with its own set of limitations.

Travel to and from Metro City
As of right now, you can only travel to Metro City. All ways of getting out are pretty ineffective. This includes: You're more than welcome to try. If you walk to the very edges of the city limits things will start to get hazy, and you'll appear again on the opposite side from where you started. If you were to try and fly out, you'd be able to get about 20 kilometers up before hitting a kind of invisible wall preventing you from going any further. If you try to teleport out, you'll wind up at a random location within the city.
 * flight
 * teleportation
 * walking/travelling by foot
 * driving/mass transit/travelling by boat
 * ....etc.

Just know that all your efforts to leave will be pretty fruitless.

Communication
Communication is limited to the confines of the city as well. This includes: The city does have its own internet service, its own phone lines-- but they are limited by the boundaries of the city just as the inhabitants are.

 * email/internet
