A little game I've seen on some other forums. What we do is one person wishes for something and you have to grant it, then corrupt it. e.g.
"I wish I was a level 40 on H.A.W.X"
"Granted, but at level 40 the game blows up in your face!
I wish for a Lamboghini Diablo..."
Geddit?
Let's try....
I wish for LOADS of money!
