im curious to see how that works... tell me more... i kinda need more details

We build off of our previous posts, adding more details as we go. So, someone starts off with an empty slate, and they have to come up with something everyone can grab onto. Maybe describe the pub a bit, or its clientele, or casually drop references to the evil overlord dictator that lives down the street. Then the next person jumps on, and could, for example, describe their character sitting down next to the first one - glancing nervously, of course, at anywhere [i]but[/i] the evil overlord dictator's thought police standing in the corner of the room. Then, in the next post, someone decides to play the previously-NPC thought policeman, so they start writing from their perspective, and edit their character sheet so that their job as thought-policeman is more clear.

That's three posts that just take what we already have and add a little to it. But by the third post, we've already got some basic potential plot points and setting - clearly there's an evil overlord dictator with thought police in the [b]pubs[/b], and while this could be modern, sci-fi, or fantasy, it's definitely dystopic. However, you can already jump off those few established things and add even [i]more[/i] to it. Maybe these characters are resistance fighters, secretly meeting in this pub to try and overthrow the evil dictator. And there's also a lot of unanswered questions, like, are there elves here? What about ray guns? [url=http://geekoutlaw.com/wp-content/uploads/2014/08/P1050682-Large1-e1408607379816.jpg]Elves with ray guns[/url]? So you just hook onto one of those for your next post, and maybe casually mention these sorts of details in the background as you push your character around the world.

Any arching plot to it?

Animus has it; the plot is what we make of it.

I want to do something like this, and would participate, so long as I know the era/genre.  I'd assume it's medieval-fantasy, bu still - no harm in asking.

We wouldn't know the genre until at least the first post. Even then, I'm not sure how definitive we could be. Note my response to Satoshi Kyou concerning elves-with-ray-guns. We might have a standard fantasy setting; we might not. It all depends on what we establish as canon.
