I saw a few of these and decide to see how would the community of Haven would go about it. In this game, you have to twist the wish of the poster above you that it affects them negatively. For example, if someone wishes for godlike powers, I would twist the wish so that can only use said power when it is 1000 AD so they can't use it at all (Time Travel doesn't work because that is before the wish was granted). Then I will make a wish in which the next poster will corrupt it.
Since there isn't a poster above me, I will start with the wish.
I wish for a cheese sandwich.
