I can see why people think this is a spammy topic, as you have to post to participate. But all forum games are like that aren't they? There is a set of rules, and you don't just post for the post. It must have meaning. You must have thought about the post.
For that reason, I'm willing to give this a try. If it turns out that people are careless with their post and they just play to post, then it'll be locked eventually too.
