Or just go on a flash site like kongregate and play it there for free >_>
So far all I'm hearing is that it's got more atmosphere (as in text describing how the world is reacting) and different way the world responds mechanically, meaning you just have to learn a different way to evolve your organism. Doesn't really seem worth paying money for.
It's reminding me of flappy bird. Taking a game that has been redone on flash websites many times and monetizing it.
The flash game, for all the good things it does, is ridiculously basic. It's not Flappy Bird so much as it's... I don't know, Dungeons of Dredmor? Take the basic premise of the original and pump it so full of new things that all that remains the same is the basic concept.
In Pandemic, you can play in one of three ways, and every one of those is practically the same - the difference is in a basic starting ability and the balance between visibility and infectivity.
In Plague Inc. you have... well, a lot more than 3 disease types, and
every one of them plays entirely differently. The Bacteria is the only one that plays similarly to the old Pandemic, and even then you
recover points for devolving. Its special abilities focus on resistance to environments. The Virus, the first disease you unlock, returns the "pay points to devolve" thing, but for a reason - its abilities center around uncontrolled mutation, changing the required tactics entirely, as you must race to infect the world before your disease becomes too dangerous and noticeable, and either gets slapped with a cure or kills all hosts before spreading everywhere. The Fungus (I think that's the second unlock) changes it again, being nigh unable to spread normally and having extreme trouble moving between countries, but having abilities that infect additional countries through increasing evo point payments. And so on, and so forth. It is an entirely different game from Pandemic, with only the basic premise remaining the same. The Evolved version might not exactly be worth the money, but with some 25% or 33% sale it should go quite well. And of course the original mobile version is quite good. Excellent timewaster.
