What specific good does Catholicism attribute to play and entertainment?

In cases where a leisure, entertainment, play activity is questioned for its morality, the moral analysis tends to hinge on at least one *evil* aspect of the activity—one that either glorifies an evil (e.g., violence in video games) or is evil in and of itself (e.g., pornography or stealing lunch money from sissies). However, if we agree that *evil is an absence of good*, and if we agree that leisure, games, and entertainment in general are *not evil*, we must be able to recognize some *inherent good* in those activities, or in the active participation thereof, for the activity to be **not evil**—and therefore *good.* For the leisurely challenged, examples of "leisure and play" include things like: * Sporting events (either participating or watching) * Dancing * Video games * Board/Table-top games * Building unnecessary things out of: * Legos * Popsicle sticks * JavaScript * *And other activities not done with a practical purpose in mind.* **From a Catholic perspective, what is it about these types of activities that is *explicitly and specifically good?*** Furthermore, should we (and can we) as Catholics be able to attribute some specific good to each particular form of leisure, entertainment, or play? Or, are there an overarching "leisurely good" that applies to any and all activities that are not explicitly evil in some facet?
