The mission is to retrieve a stolen chest! If you read the dialogues they take you thru the journey and explain why things are done along the way. Not a hard game but still captivating and fun. I don't know the skill level or interest of the people giving bad reviews, however perhaps not every game is for everyone.
I love these games and this is hard for me to say...boring. I lost interest quickly (within 10 minutes) not compelling and fun like the others. Maybe an example of trying to make to many versions of the same game or the game brains behind it becoming too reliant on fan enthusiasm.
Imagine a sunny day at a cozy Parisian cafe. People are walking around, drinking coffee and laughing. Suddenly a bright flash wipes out all life on Earth!
