MyMiniCity

I found MyMiniCity, which we can build virtual cities on the Internet.
It's similar to SecondLife in a sense.

It's so simple to start:
Choose a country and decide your city's name.

The cities become bigger and larger when they are accessed.
It seems the development of the cities is not always good:
For example, too much population, crimes and environmental problems like deforestation.
It's so realistic!

My city is here: Naotie
