Dimensional conflict: diversion vs. expression

While I mentioned in Three-dimensional games that games with the greatest magnitude in all three dimensions will be considered the best, this isn't to say that dimensions won't occasionally come into conflict with each other.  In other words, it is possible that attempting to increase the magnitude along one axis will decrease the magnitude along another axis.

I want to focus on a specific conflict that can arise when trying to maximize the magnitude along every dimension: the conflict between the demand of diversion to fill time and the demand of expression to reduce the time filled.
