Just bringing back this kind of game, because it can make for some interesting questions and answers!
It's fairly simple, present the next poster with a question in which they must choose one of two options, the next poster answers and asks a new question - just like the social game, really. My experience tells me that many prefer to keep the two options of the question related in some way, but it isn't necessary.
Example:
A: "Would you rather have tea or coffee?"
B: "Tea, because coffee is usually too bitter for me.
Would you rather go cow tipping or horseback riding?"
So, to start off:
Would you rather be a super villain or a super hero?
