My group is doing our own "sideshow" campaign - an alternate, on-going campaign with storyline results being decided through gameplay.
The set-up: Each player has chosen a different clan and we're playing with the following arrangements:
Every player may only build their beginning deck from 1 (!) Core Set. Why? Challenge. You must use every card available for your faction (but you do not need to use all copies).
Whenever you win a game, you are awarded an "Imperial Favor".
Every broken Province is set aside; at the end of the game, the losing player must eliminate one of those Provinces from their deck.
Whenever a Dynasty Pack comes out, everyone may add their faction's cards from it at the cost of an Imperial Favor.
Any unique character that is eliminated during the game is "wounded" and may not be used in the next game; they are Healed after that player's next game and may be used again.
Players may spend an Imperial Favor for the following effects:
Favor in Court: You may add 1 card to your deck for which you don't need to pay Influence.
Favor in Battle: Spend before you draw your opening hand; you may play one non-unique character (with no extra fate) for 0 fate from your opening hand.
Favor in the Monastaries: You may Heal up to three Wounded characters before your next game.
Favor of the Scholars: Spend before you declare your first Conflict of a game; you may view one face-down province.
Favor of the Cartographers: Add one of your eliminated Provinces back to your deck.
Favor of the Merchants: Add your faction's (and any neutral) cards from a Dynasty Pack.

Story Results: Every win for your faction gives you 1 Advancement point.
After 10 Advancements, your Clan gets a story result:

Crab Wins: Reinforce the Wall -
Crane Wins: Bountiful Harvest -
Dragon Wins: Discovery of Ancient Scrolls -
Lion Wins: The Right Hand of the Empire -
Phoenix Wins: Discovery of Secret Knowledge -
Scorpion Wins: Secrets Under Secrets -
Unicorn Wins: Free As the Wind -

So why am I posting this? We'd like to throw it open to the community at large and track ongoing results. If you'd like to join in, post your faction, play some games, and let me know how it went!

Here's the results format:

Game One:
Crane against Dragon.
Crane wins (1 Imperial Favor, 1 Advancement).
Daidoji Nerishima is Wounded.
Togashi Kazue is Wounded.
Dragon loses Restoration of Balance.

If you'd like to join in, we'd love to have you! If you have some suggestions for more fun stuff, let me know.

Banzai!
