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.
Okay, Person C. You can teleport, but only one bodypart at a time. My wish: I wish I could charge phones with my hand.
Okay, Deestan. You can charge phones with your hand, but only very slowly and the phone gets uncomfortably hot. My wish: I wish public transport was free.
Okay, Pankkake. Public transport is free, which is a great boon to the plebs but obviously have the the car manufacturers and other corporate lobbyists irked. They lobby the government until funding is severely slashed; eventually passenger train infrastructure starts to crumble, busses are frequently out of commission, and no one can get anywhere on time using public transport.
I wish everyone in the world always had enough food to satisfy their basic nutritional needs.
The food is absolute nauseating in taste, despite being extremely good for people health.
I wish for an efficient way to create fusion energy to be discovered.
Wish granted. This causes weapons of mass destruction that rely on fusion tech to be much easier to acquire, plunging the world into a new cold war.
I wish I could shape-shift into any animal at will.
I’ll start off: I wish I could teleport
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.
Wish granted. You get the notebook***.
I wish I could stop time.
***accompanying magic pencil granted separately.
Wish granted. But once you use your powers for the first time you realize that you cannot unfreeze time, and so you (along with the rest of the universe) spend eternity frozen.
I wish I could cure any ailment with a single touch.
Granted. No one in your country stays sick. There is an explosion in the elderly population. The pension fund runs out. Millions starve to death.
I wish I am all-knowledgeable.
