I disagree with the people the say the missions are hard but they are really not to me I play this game all the time all day and I get the missions done really quickly and it is true that the ads interup the game witch is really anoying to me but they dont take long and they take me back to my game but...... what I am trying to say is you should try this game it is really amazing and fun and when you play this game you will be just sitting there all day playing and not even notesing so try it
