No, Modestgoddess--I wasn't seriously proposing a three-hour time frame. Just mapping out what could occur if we did. Any time frame wouldn't really work here, as tsuwm pointed out. I was simply agreeing with him by showing what could happen, even with a three-hour time frame. Even with a 24-hour time frame, giving everybody a chance to respond to a proposed word, how would we determine which one of the responders had the right to propose the next word?

The game, as proposed, simply won't work. But it does sound like a great game for word hounds, and particularly for argumentative word hounds.
