too much emphasis on Europe. Better have a Europe round, with europe enlarged, o/w it's pretty daft - if you know something's in America but not where it matters, if you know something's in england but not where it doesn't.
Easy game. Concentrating on Blue recommended for most challenges, stacking the +1 bot aura is godly. In an effort to make the game as balanced as possible variation via more unusual cards has been sacrificed. Contamination stays locked after all challenges completed, game speed resets every game. A game like this really needs MP though.
