Inspired by games like Trine, Magica and several “choose your adventure”-books I suggest a premise for a game. 
I’m looking for a few players who will take up arms with me as one of the “archetypes” of the fantasy genre. As such, [u]please leave the realism at the door.[/u] The characters should be based on stereotypes or “tropes” that are easily recognised and played with.
Together we will go on an adventure through a fantasy world where nothing is decided beforehand. We will develop the world around us as we explore and experience it and all of its dangerous inhabitants. 

This will not be as easy as it sounds though, to play you must:
Accept that your character can and will fail, and use this as a tool to create a more interesting story.
Be able to produce around two paragraphs of text per post (This means both “no one-liners” and “no wall of text”).
Be able to push the story forward with [u]every[/u] post.
Accept what is happening to the world, situation and your character.

[color=ed1c24]Important info for everyone![/color]

I've had a thought about posting length and arrived at the conclusion that it is suboptimal. The rules states two paragraphs of text per post, I believe that three paragraphs will be better suited for this game, and it will make things a lot clearer.
In each post we will not only have to react to whatever has happened since our last post and write out what we want to do next, we also have to resolve whatever actions the guy before us wants to do, in two paragraphs it will get messy.
With three paragraphs to work with a post may look like this:

§1: Results of previous poster's actions. This way the player won't have to read the entire post to figure out what happened or if it is irrelevant to their own character.
§2: Reaction to what has happened, new info, actions, thoughts, feelings... You get the drill.
§3: Declaration of next course of action. This is what the next poster will need to resolve.
(At the end of your last paragraph, please use the mention function to let the next guy know it is time to post.)

Rules in the game:
[hider=Posting order]
To avoid having one player doing 90% of the posts (or only 10%) we’ll use a posting order. The only time this will really matter is right at the start of the game because the player who goes first doesn’t have anything to react to. Once we’re rolling it should run smoothly.
The posting order is an important part of the balance of the game, as well as a system to make sure that everyone is keeping up with the story. Please keep this in mind.[/hider]

[hider=The next post decides the outcome]
This is meant to balance the gameplay and make sure that everyone has something to write.
How does this work? Every time you intend to interact with the world (Try to kill someone, open a door, jump into a hole, force a merchant to give to the enchanted sword…) you leave the result open ended (As in “I try to hit the guy with my sword” “I send a fireball toward the bandit” “I sneak up behind the guard the try to steal the keys”) The next writer then starts her post by deciding the outcome of the action and write how it plays out.
[b]This means that you take limited control of another player’s character, and in turn allow someone else to control yours.[/b][/hider]

[hider=Keep it short and sweet]
In this game we’re supposed to push the story forward with every post, that means that we can’t just stand around waiting for something to happen. At the same time, failure is an important part of the game that should be encouraged. However, as the resolver of actions, pay attention to the flow of the game. Don’t hold your friend back just because she didn’t figure out exactly what you wanted her to do.[/hider]

[hider=Don’t get stuck]
If at first you don’t succeed, try something else. If you missed with your attack, don’t just attack again, try to find another way. We’re supposed to be on the move almost all the time here, so if you find yourself in the same situation two posts in a row, try to find another way of getting out of it.[/hider]

[hider=Relax]
This game is not supposed to be a big project. Neither is it supposed to be your “main game” here on the guild but rather an amusing side-quest. Short post, low realism, sudden changes and archetypes are all deliberately put into the game because I don’t want this to become a time-consuming chore. I just want to play around and have fun, and I hope that’s what you want as well.[/hider]

[hider=What is a choose-your-own-adventure book?]most people might not be familiar with the concept of choose-your-own-adventure books. The idea is quite simple. After a brief introduction the reader (player, adventurer) is given a few choices as to how the adventure will continue, the choice will take the reader to a new page of the book and a short text about what happens next, followed by a few new choices. For you convenience I have tracked down a somewhat known duo known on youtube as Simon and Lewis from Yogscast, as they play one of these adventures: [url=https://www.youtube.com/watch?v=OdETCgyrnLc&list=PL3XZNMGhpynNoFzKiTxZK5s1KfdWzBEpy]House of hell[/url][/hider]
