Could've been such a nice one...
I liked the first Pandemic, it was an interesting idea and the way the gameplay was designed it worked very well. But this game, while having some nice improvements, is quite inferior to its precessor. The reason is very simple: luck is just too dominant in this one. Don't get it wrong, you need some strategy and brainless clicking won't get you anywhere. But I've tested the same (working) strategy on 20 runs, restarting the ones that let me start in either greenland or australia, given starting in those hard to reach ones is already a huge lucky boost. The results have been sad, a few times my virus died in the starting country in three or four turns since it didn't infect anybody else in the country, other times it took (game-time) weeks to infest certain areas or up to 23 days to erase the last remaining 1% of mankind (at a lethality rating of 6). Not to forget the numerous times an infected airplane made it to a different country but the infected person died right away (while the virus was at lethality 0), which made the already high randomness of success (in any area of the game) even more obvious.
So altogether it's a pity the nice idea of the first one (where the only real randomness was whether or not you'd manage to get to western europe) has been almost totally ruined by the insane influence that luck has in this version (hence my low interactivity rating, I don't consider pressing the "infect" button 10 times and hoping for the best too interactive). Oh and you should prolly re-name the highscore list into "Lucky Bastards", since it's showing their luck much more than their skill.
