I've considered running a D&D-inspired (or, at least, Drowning & Falling-inspired) Wushu game where one trait is always a race, one is a class, and one is a stat.  These are as loosely defined as possible, and there's no pre-made list of them, so players are encouraged to steal or invent any traits and ridiculous combination they want.  ("Demi-Wemic, Paladin, Intelligence."  "Were-Tarrasque, Ranger, Rope Use."  "Rakshasa, Psionicist, Perception."  "Arab, Dervish, Story-telling.")  They also get to assign the numbers however they want (Black Knight 5, Appearance 4, Dragon 3 is very different from the reverse).  Finally, they choose some kind of character trait in the lit 101 sense, like Loyal or Ambitious or Drunken or Defiant or something, which is their Distinction/Flaw.

Start with a tavern meeting scene.  Choose one player who gives the taverns name ("Prancing Pony," "Rampant AI," "Mocking Lungfish").  All players briefly narrate their first appearance 'on camera' ("I walk in from the blizzard and bellow for an ale," "A cloaked and hooded figure sits in a shadowed corner smoking a long pipe," "The door at the top of the stairs bursts open and I run down, clutching my pants around my waist, chased by a furious Inkeeper demanding blood for his daughter's honor").  Then a challenge of value  (5+numplayersx3) with Threat 2 starts.  When that runs out, the tavern-naming player gets to declare the party formed.  The player to his left narrates the old man who gives the party a mysterious map/key/tale, whatever, and describes the first adventure scene (attacked by savage natives as you near the island/enter the first room of the dungeon/quest for the enchanted castle) with the same challenge value, and same basic narration at the end (immediate results of success/failure, .

All my WUSHU ideas end up GMless.  Most end up ridiculous.  Feel free not to use this one.
