Quoted from DCFAN:Make sure to have some of the callouts have energy/excitement. Don't have all the callouts be monotone observations in a pirate accent.
I'm all about the super jackpot callout being extreme and a feeling of accomplishment as well. But I think they have the callouts already done from the actor who was in the movies. Not sure what they can do, but if they can put in the most exciting callouts for jackpots and supers, to me thats the best feeling in the game when you hear those callouts.
