I really don't know why I thought you might have been content with the product of the song games; you phrased it perfectly with " rhyming a full story is very difficult." I think that embodies everything that terrifies me about improv. The idea that you are expected to create a continuous story rhythmically while rhyming. I definitely don't really look forward to the songs, but am kind of intrigued by the challenge (I'm always both surprised and disappointed with each singing game).
