Writing games are tricks, exercises, things to try to get your writing brain in the mood. I find them useful when a story's giving me trouble - I can't think of a way out of the corner, or I can't think of a corner to get into, or I'm just not feeling in the right mood to write that story - as well as generating new ideas, and just keeping my writing-mind in shape. And on the plus side, they're usually fun to try, and you can end up with the germs of some great little stories.

Zombie apocalypse

I'll admit this one comes straight from office geekery, but it's still fun. Take a look at your surroundings, right now. Now imagine a horde of zombies advancing - and I'm not talking the slow-shuffling, scary-as-your-biscuit-tin zombies, but rabid attack freaks.

What you have to hand is what you can use to mount a defence. How well does your office or house (wherever you are) stand up to zombie attacks? Where are the choke points, what rooms are likely ambush zones? What would you do? Would to try to rescue your co-workers, or leave them to their own fate? Would you run or hide? Where would you go?

Zombies are attacking. Write your escape.
