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
Pattern memorisation and precise platforming with a solvable boss-order route.

Execution · Practiced Mastery
Open-world reboot of Mirror's Edge centered on free-running across the city of Glass.
Mega Man 5 leans Execution (Practiced Mastery); Mirror's Edge Catalyst 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 5
Precise jumps and buster timing through gauntlet stages
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 5
Robot Masters 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 5
Every stage and boss is identical each attempt
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 5
Weapon-order routing and pattern memorisation solve the game
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.
