Plague is a strategy game that challenges you to create a disease that can kill all of the people in the world before a cure is discovered. In order to do this, you have to tweak your disease's characteristics to make it as hard to cure and as easy to spread as possible.
Realistic scenarios: In order to successfully spread your pathogen across the globe, you have to deal with multiple different types of challenges that mimic what would actually occur if there was a fear of a pandemic sweeping from country to country. For instance, the governments of various countries can shut down their airports to prevent infected individuals from entering, and even the country or region that you choose to infect first has a significant impact on your disease's ability to spread.
Levels of difficulty: When you start a new game, you can choose the level of difficulty you prefer to play through. These include Casual, Normal, and Brutal, and the differences between them involving the behavior of individuals determine to a large extent how easy it is for your disease to spread. Especially for players new to the game, it's nice to play through at few times in casual mode to get a sense of how things play out before jumping into a more challenging situation.
Hidden costs: Although the app only costs $0.99, it's impossible to play a game, even in casual mode, without paying to unlock some additional pathogen features. Considering the quality of the game, the cost of unlocking the entire gene pool, which is $7.99, is not exorbitant, but it's a little deceptive to price things this way because the initial $0.99 you spend to purchase the app doesn't get you anything at all.
Plague is a well-crafted game that is engaging and fun to play, despite the somewhat morbid goal. The hidden costs are unfortunate, but when you expect them, they don't have to be a major drawback. And because you can experiment with many different types of pathogens and adjust so many different characteristics, there are almost endless possibilities for this game.
