Trends 2012: Plague Inc.

The world was supposed to end a week ago.
Who would believe that
the end of a long and rather accurate, celestial-based calendar of an ancient American civilization
would coincide with the end of the world?

Aren't we happy on new year's eve?

Even Jesus don't know when.

But how would it happen?
Let's take a look at one possible scenario:
The Plague

You play as the Plague
and your goal is to make it the Plague that will end it all.
The Plague evolves over time and mutates.
It is strategy and you decide how it infects, spread, and kill
by choosing its evolution path and other things.

The app was developed by Ndemic Creations and Miniclip.
It was first available on Apple store on May 26, 2012, selling for $0.99 and now with 2,000,000+ downloads with an average rating of 4.5 stars from 65,500+ users
then on Google play on October 4, 2012 for free, now with 1,000,000+ downloads and with an average rating of 4.6 from 100,000+ users.
I give it 4 stars.
Expansions are downloadable with a fee.

Or, just maybe, it won't be a one great event but a series of events.
