Out of the three my favorite would have to be Monopoly. Normal monopoly but you are split up into different groups. Each class has advantages or disadvantages. That makes the game either easier or harder passed off the class you fall in. For example if you get the lower class, there is a good chance you will not win. Some cases however you may be able to pull off a miracle.
The McDonalds game is simple and it shows the process of how they get everything to the restaurant then to the customer. I think its a cool way to show the process of what they did instead of playing a video or something like that.
