No doubt the DUDE SHINOBI video game is big in this comic, but I've always wondered how it plays out.
From what I seen and heard, it's got a Double Dragonesque, Ninja Gaidenish feel to it. I was wondering if you can incorporate the infamous "Game Over" screen from the Ninja Gaiden arcade game (where Ryu Hayabusa is strapped to a table as a buzzsaw lowers toward him) and have DS be the sacrifice instead.
Nostalgia is very huge. Lots of 80s elements are out there, Explore them all at your own leisure.
