I agree with all of this.
Personally, I would like to have a 20's game followed by reserve grade followed by first grade. That's a great day at the footy. But only worth sitting through if it's quality football. The bottom line is I think we would all prefer quality over quantity.
But I don't think the Titans are going to be trying to change the structure of the NRL to get us fans a better game day experience. I'll take my chances of getting a tasty hotdog, chips and drink prior to heading into the stadium before I start worrying/wondering when/if they will be bringing back reserve grade.
As DIEHARD said, banner competitions and rewarding Titans fans who make an effort with costume/apparel with ground appearances and/or competitions would be a good way to engage fans.
Random prize draws would be a good way to engage the general crowd.
Music grabs is a tried and tested way to create atmosphere.
What is something new that hasn't been done? You know that blow-up blimp thing they fly around the stadium? What about having blimp wars, between 2 opposing fans? First to knock the other one down wins! Yeah!!
