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

Execution · Practiced Mastery
Tight platforming execution against fixed boss patterns with a solvable upgrade route.

Execution · Practiced Mastery
Open-world reboot of Mirror's Edge centered on free-running across the city of Glass.
Mega Man X3 leans Execution (Practiced Mastery); Mirror's Edge Catalyst leans Execution (Practiced Mastery).
Mega Man X3 leans a little harder on execution, though the gap is small.
Mega Man X3
Dash-jump precision and boss dodging demand tight inputs
Mirror's Edge Catalyst
Flow-state parkour with timing-based combat
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mega Man X3
Mavericks cycle fixed attack patterns
Mirror's Edge Catalyst
Enemies are scripted obstacles
Mirror's Edge Catalyst leans a little harder on variance, though the gap is small.
Mega Man X3
Nothing random - every pickup and enemy is placed
Mirror's Edge Catalyst
Open world is static once explored
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mega Man X3
Weapon-order and upgrade routing is a known solved sequence
Mirror's Edge Catalyst
Time trials reward optimal route discovery
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.
