Changing my review. The game is utterly frustrating and unplayable as it randomly makes the menus disappear after loading a saved game, freezes the game and grinds everything to a halt. It's impossible to play the unlock all countries mode unless you intend to do it in one 12-hours session. It is a shame, as the concept is well designed and the game is very addicting. But it is unplayable, and unless this is fixed in the next few days, I will uninstall and change the rating to 1 star.
