Easy game to play and the object of the is to make a wish. Then the person to posts must grant it. But they must put a "add on" to the wish that ruins it!
For example.
(I post) I wish I had the most money of anyone in the world!
(next person might reply) Done but the world stops using money and switches back to rocks as currency.
Okay let me start..I wish for a peaceful world
Well your wish is granted I teleport you to the moon where you are the only person there...
I wish for true love
