Simple game, a person makes a wish. Anyone else can “corrupt” it. Then that person makes a wish of their own, and the cycle continues.
For example:
Person A: I wish I had 1 million dollars.
Person B: Wish granted, but they are Monopoly dollars. My wish: I wish I could fly.
Person C: Wish granted, but sustaining flight requires 500 calories per minute. My wish: I wish I could teleport.
etc.
Wish granted, but coordinates span the universe. You mess up, teleport off planet, and die.
I wish I could fly.
edit: subconsciously copied the flying part lol
Wish granted, but you can only fly when no one is looking at you.
I wish I had the ability to predict what someone was going to say before they could say it.
Wish granted. You become popular, now the FBI, CIA, NSA, DEA all want you, and you lose control over your life.
I wish I had the ability to push the stock prices up when I squint hard enough.
Wish granted. Stock prices go up the harder you squint but conversely plummet when you don’t, leading to an apocalypic market crash that can only be avoided by frequent squinting throughout the day. On the plus side markets close after 4pm so you do get to rest you eyes a bit before the next day :P
I wish I had a notebook, that whatever I drew in it would immediately come into existence in front of me.
