I tried this on Boardgamegeek and got many interesting (and sometimes hilarious) responses:
According to tweetdeck, one of the trending:worldwide topics on twitter is 6 word stories. Those can be amusing, and I once asked Britannia fans to write the story of my game Britannia in 6 words with good results.
But this time I have something harder in mind: say what a game designer does, or what he is, in 6 words. Or if that's too challenging, try 10. I have a version of both, but I'll hold off on it for now.
