I just came up with a new game. Let's try and see how popular this one can be.
The first persion buys something he/she would really like to have.
The second persion sells it then buys something else, that he/she wants (not persion 1).
And so on. For example:
Persion 1: I buy a racecar shaped bed.
Persion 2: I sell the bed and buy a pearl necklace.
Persion 3: I sell the necklace and buy an iPhone.
You can buy a fictional item if you wish, but you can buy only 1 item at once.
