I found Agatha's Song to be pretty special. It wasn't crazy fun, it wasn't long, but I found it a much needed moment of respite in the wasteland, I listen to her radio station pretty frequently now. Her violin is a beautiful contrast to wandering the desolation, especially at sunrise or sunset.
For sheer giggles I enjoyed how ridiculous the Superhuman Gambit was. Pure silly!!
