The mods generally allow them in the off-topic forum unless the thread gets stupidly out of hand.
But I'm confused how you can have a person below you game. Are you supposed to say a random trait and hope that there is someone on the forum who meets that description and that they will post? What if I say, "The person below me is a whining narcissist." That would probably kill the thread because no one would want to have themselves labeled as a whining narcissist. What if I say, "The person below me is a unicorn." Again, thread over because there are no such things as unicorns. But really, the point is moot because, in fact, there isn't anyone below me. How can I say anything about someone who doesn't exist? It's an existential puzzle.
