Definitely worth giving a try!
I'll admit at first I thought that this game wasn't going to be all that great compared to the other Pandemic games, but I was happily surprised once I got the hang of it.
The good: I personally believe they did a great soundtrack it fits the apocalyptic aspect of the game well. Depending on the player it should be easy to wipe out the human race within an hour or 2, way faster than it would take most people to finish the other two Pandemic games (assuming they successfully killed off mankind, not just most of it).
The bad: Though the music is alright after a while of constant replay it could get really old really fast ¬_¬ still though that shouldn't stop you from enjoying the game. The amount of points it could take to infect another country can be a little annoying. They got rid of the symptoms.. I believe that's what made 1 & 2 more in depth.
In some ways Pandemic EoM is better than Pandemic 2 and vise versa.
A worthy addition to the Pandemic family tree! A great game and you should definitely give it a try!
