Metro ride through Paris

Unfortunately, I am very disappointed with the game. On various lines can indeed pass control the Metro under Paris, once even as Hochbahn overlooking the Eiffel Tower, the Seine, Notre Dame and diverse Parisian townhouses, open the doors of the train and close, slow down and start again, but that it has already. No major challenges so quickly keeps boredom catchment. Unfortunately. But perhaps my ideas and expectations were set too high?
