Players like to think their plans are well thought out and original. Of course most plots are recycled to a greater or lesser degree from other sources (which is a fine thing, as long as you introduce enough variation to disguise the source), so most of the solutions will tend to be as well. It's when the players start recycling their own plans that something needs to be done to shake things up.
