I think there are still things that google docs wouldnt be able to do as well as something like WikiTale. It can open up the floor to collaboration with people around the world.

I like the game idea. It's something I would like to look into developing as apart of WikiTale, after we have the core features done. Maybe instead of selecting a winner, we set a time for each game and see where the story ends?

Maybe this chatroom can save logs to user profiles to be viewed or downloaded after each game
