I have the game now (without crashing on my Galaxy S4 played twice, once lost the bet and won once. The game features very much variety, I think you could more often through play and try out the various routes around the world. Good English is important and you should inform about the book, because some "facts" in the game look quite funny (current cities, etc) if you do not know the book. All in all a nice game.
