What to write, what to write...

After brainstorming for most of yesterday and this morning, I am now officially down to three possible stories for NaNoWriMo. Unfortunately, they are all very different to each other, and for the first two I have basically no more ideas than those already in the description. The last one is more or less a retelling of our Doctor Who campaign, so I am very clear about what to write there. It's more like a fall back point in case I get stuck and need something else to write ^^;;;

Please, have a look at my ideas and tell me which one you'd think would be most interesting:

 

CHILDREN OF DISCORD

In the greatest palace of the capital lives the Count of Discord, forever caught in a golden cage. He wishes for nothing more than to be free again, and so he sends his soldiers out to bring him the country's children, hoping that one of them would be suitable as a successor to take his place. But when the boy Archille is kidnapped, eight-year old Colette travels with infamous warlock Marius Lalande to the city to save the children and to bring her brother back home.
A Victorian steampunk fantasy.

 LEGENDS

A metropolis, struck by desaster and ravaged by nature. Its citizens: desperate and without hope. What this city needs is a hero. But how do you choose one, if there are so many of them. And how can you rely on them, if all of them are busy with their own problems?
A superpowered dystopia.

 CODEWORD: ALCYONE

One summer day in 2010, the peaceful lives of PC Abigail Clearwater and electronic shop employee Jordan Kelley are derailed into something very much more adventurous when they stumble upon an alien in rural Nether Stowey. Swiftly, they find themselves embroiled in a tangled mess of aliens, time travel, and an international task force that may be up to more than the common greater good.
A retelling of my ongoing Doctor Who RPG campaign.
