Plague Inc is a pretty fun strategy game I've been playing the last couple days, where you create your own killer virus/bacteria/whatever and try to infect the planet. The game is won when you kill everyone on the planet, you lose if a cure is discovered.
Obviously in the cell phone version the game is free and you can pay to unlock other types, but you can unlock some, probably all things from playing.
The in game menus are actually pretty nice, while you sit and wait for your plague to spread.
you can use the dna points to evolve your plague so that it's harder to cure and/or becomes fatal to the people infected.
anyway, I thought it was pretty damn fun and thought I'd share with you guys. I found out that they have a steam version too apparently. I may grab it for some time wasting, if I can start staying on the computer for longer periods of time. Here's the full website if you want to check it out http://www.ndemiccreations.com/en/22-plague-inc
