Playing Ninja Gaiden II is not merely playing a video game; it is a live-action, accelerated simulation of neurosurgical calculus. There are so many interlocking variables occurring at any given micro-second that the player must calculate and execute with the precision of a scalpel dancing across the sub-cortical white matter, simultaneously tracking Ryu's Vectorial Position relative to the enemy centroid mass, the Damage-to-Kill Threshold for each individual hostile in the current enemy composition, and the Vulnerability State & Limb Separation Index of every target. This is functionally identical to the factors a Consultant Neurosurgeon manages during a Deep Brain Stimulator (DBS) implantation: tracking the trajectory of the microelectrode through the thalamus and maintaining perfect stereotactic co-registration with the pre-operative MRI data, all while the patient's vitals fluctuate. One could argue, with the intellectual depth of a dried puddle, "JUsT UT AnD yOu WiN," but this is a gross, offensive oversimplification, the equivalent of telling that neurosurgeon, "Just put your hand on the head, and the brain surgery happens." What these denizens of simplistic button-mashing fail to grasp is that the true artistry of Ninja Gaiden II lies not in the brute force of a single move, but in the micro-decision tree that remains constant throughout all gameplay. Three-frame window of perfect parry: a precise moment that guarantees tactical repositioning or gaining positional superiority. The Wind Path cancel that precisely positions Ryu outside the blast radius of the exploding incendiary shuriken.
