It should be full of joy

I dislike Quora's decision to hide answers behind a login, which makes me go to the site infrequently. That said, Robert Frost, engineer/instructor at NASA, answered this question perfectly:

Why do some intelligent people care to remember and understand a massive amount of details (characters, relations, interactions, events) of completely imaginary and excessively detailed settings?

Joy.

Life is short. It should be full of joy. Imaginary worlds are fantastical and thus more interesting than the real world. That brings joy.
