I found this game on some old forums I used to visit.
Pretty much, you wish for something that you think would work to your advantage, but then the next person would determine the outcome of your wish that no longer works to your advantage.
All of the wishes and responses re meant to be hypothetical.
When you are replying to a wish, use your imagination for the negative outcome of said wish instead of basing it on reality.
1) Person A: I wish to be invincible!
Person B replies: Granted, but your friends and family die before you and when the world ends, you'll float around in space for eternity.
2) Person A: I wish for a mansion!
Person B replies: Granted, but the person who sold you the mansion forgot to mention that the mansion is haunted.
I wish for a brand new car!
