The infection has begun and it’s up to you to strategically spread and evolve a deadly plague to bring about the end of the human race. Saving the world and being a hero is honourable, but decimating the world with a deadly infection is a whole lot of fun — even though it shouldn’t be.

Think about it, what would happen in real life? I’m pretty sure everyone here in the real world isn’t perfect. But not in plague. Apparently every type of resource possible grows on trees, and every other disease is suddenly non-existent as soon as you start. I’m my own personal opinion, mega brutal should be what brutal is. Mega brutal is more like, “Sick people disappear off the face of the earth.” “Everybody lives in high tech state of the art homes that purify you as you wake up.” “Doctors not only sell their children for money to invest in the cure, but they were each single handily taught and trained by a wise monk in Nepal as children, Is able to complete a common knowledge test even though the sickness the currently have makes them insane literally, and have had their brain replaced by an A.I. alien technology that is yet to be discovered.” Oh yeah and everybody is a doctor regardless of what they actually wanted to do when they were kids. I will be doing just fine slowly infecting the population without any severity and then there is an “Anonymous blood test in one of the three countries I have infected. I face palm and shake my head knowing that those types of things can even happen. It’s fun altogether but mega brutal might as well be called impossible for certain plague types.

Incredibly unrealistic

This isn't a realistic situation like they say it is. Every country has unlimited supplies and money and know exactly how to counter and cure every disease. Seriously, whenever I upgrade anything in transmission while the severity bar is as low as possible, every country immediately knows what I did and takes immediate countermeasures. There was one game where I had over 200 dna in my transmissions section and no one in the US was getting infected at all, and Im not even figuratively speaking. Not to mention Africa, which has every country distributing bottled water, like how the actual hell? Every country has unlimited resources and funding as well. Every country could afford to exterminate rats, birds, rodents, and give everyone bottled water and blood tests and then cure everyones diseases in those blood tests. They also knew how to cure a disease that had tumors and total organ failure. They literally cured cancer and every other organ disease there was in a matter of 2 years, it blows my mind. This world is set inside a utopia where money is not a problem. Also, after upgrading just 1 symptom, they think a new disease is present? Coughing, Nausea, and Anemia are all common symptoms, they cant assume its a new disease just from that. This doesn't make any sense. I'll give 2 stars because it does pass time well.
