head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Execution · Practiced Mastery
A twin-stick arcade shooter where flawless movement through layered projectile patterns and human-rescue routing is the skill ceiling.

Execution · Practiced Mastery
Memorising spawn patterns then executing them flawlessly under one-hit-death rules.
Nex Machina leans Execution (Practiced Mastery); Super Contra leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Nex Machina
Rapid dodging through layered lasers and bullets is the entire test
Super Contra
One-hit deaths demand precise dodging and constant accurate fire
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Nex Machina
All enemy behaviour is scripted arcade-style
Super Contra
Alien waves follow fixed spawn scripts
Nex Machina leans a little harder on variance, though the gap is small.
Nex Machina
Enemy arrangement has minor randomisation between waves
Super Contra
Nothing random once spawn patterns are memorised
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Nex Machina
Human rescue routing and weapon pick sequencing reward study
Super Contra
Memorising spawns and weapon routes is half the run
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
