It's Lonely in Bloisville ...

... though if you click here, you can increase the population and help me make it a better place. (Nothing to join; just click!)

Or, create your own and hope enough of your friends click your URL to make it a better place.

Site apparently doesn't rely only on cookies as I used two other browsers and the population didn't rise. (IP addy's perhaps?)

Like SimCity, though only requiring visitation from unique individuals at various URL's over time.

UPDATE:

One visit per person and day the site claims, so you can visit every day to increase the population.

And click this in addition to build industry.

Have you a city yet?
