head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
Punishing platforming execution over learnable boss orders and part builds.

Execution · Practiced Mastery
A voxel-based arcade shooter where precise movement and optimal human-rescue sequencing drive score.
Mega Man X6 leans Execution (Practiced Mastery); Resogun 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.
Mega Man X6
Cruel platforming and boss windows demand frame-tight inputs
Resogun
Precise overdrive timing and bullet-threading at high speed
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mega Man X6
Bosses are fixed pattern sets
Resogun
Scripted enemy formations only
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mega Man X6
The Nightmare System shuffles level hazards between runs
Resogun
Particle-based destruction and some randomised enemy entry points
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mega Man X6
Weapon orders, armor parts and route knowledge are essential
Resogun
Keeper rescue sequencing and phase timing are fully learnable
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.
