Basically, what you do is just say I think it'd be cool if... and then something you'd like to see happen like:
I think it'd be cool if...Hogwarts was real and I could go there. And then the next part to this game is, the next poster will say something that would make you not want to go there or do something like:
Yeah, but not if Voldemort was Headmaster. Do you get it? So the example is:
Poster #1. I think it'd be cool if (or ITIBCI to shorten things) if Hogwarts was real and I could go there.
Poster #2. Yeah, but not if Voldemort was headmaster.
Then poster #3 would post another thing that'd be cool. Get it, if not just ask and I'll explain. Okay let it begin:
I think it'd be cool if I could interview J.K. Rowling
NOTE: It doesn't have to be related to Harry Potter
M1: I think it'd be cool if...
