 The third season made several substantial changes to the show.  Female backing vocals were added to the theme songs, new events were  added, a lineup board showing the days events was shown after the  first game, a halftime show was added after the second event, and  there were several Aggro Crag changes as well. For the fourth season  (Global Guts), all of these changes were done away with (other than  the theme song backing vocals.)
