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
Open-world reboot of Mirror's Edge centered on free-running across the city of Glass.

Execution · Practiced Mastery
Executing memorised high-speed routes through deterministic platforming levels.
Mirror's Edge Catalyst leans Execution (Practiced Mastery); Sonic Generations 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.
Mirror's Edge Catalyst
Flow-state parkour with timing-based combat
Sonic Generations
Holding speed through precise jumps and boosts is the test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mirror's Edge Catalyst
Enemies are scripted obstacles
Sonic Generations
No opponent; bosses are fixed patterns
Mirror's Edge Catalyst leans a little harder on variance, though the gap is small.
Mirror's Edge Catalyst
Open world is static once explored
Sonic Generations
Levels are fully deterministic
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mirror's Edge Catalyst
Time trials reward optimal route discovery
Sonic Generations
S-ranks come from memorising optimal routes and shortcuts
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.
