This game is very simple - someone makes a wish and another person ruins it. They them make a wish and the next person long ruins it etc.
I'll start
I wish for lots of money

You get lots of money, but it's given to you in a high-inflation currency, so to the rest of the world, it's worth about $5.

* This game kind of reminds me of the movie Bedazzled.

I wish for the ability to fly.

They become depressed as everyone around them dies and all go mad
I wish for a flying monkey

you quickly learn flying monkeys lead to flying poo attacks from above

i wish for my own private island

Lack of civilization for that long time will destroy your social skills.
I wish there was a cure for AIDS

It makes you sterile *shudder*
I wish for infinate amounts of nitroglycerine

unfortunately because of it's infinite status now it has turned dormant and is not just toxic water

i wish for attack squirrels!

You wish that you had kamikaze powers and then try them out.
I wish for the best computer game in the world
