It is Simple. Ask the person below you a "If you" and answer the question " If you" question to the person above you.
Example
User 1: I would use the geass on my enemies.
If you had the ability to change the world, how would you change it?
User 2: I could stop all the first world problems.
If you had a Gundam, what would you do with it?
And so on, Have Fun!
