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

Execution · Practiced Mastery
Memorising stage routes and executing them cleanly for ranks and speed.
Mirror's Edge Catalyst leans Execution (Practiced Mastery); Sonic Adventure 2: Battle leans Execution (Practiced Mastery).
Mirror's Edge Catalyst leans a little harder on execution, though the gap is small.
Mirror's Edge Catalyst
Flow-state parkour with timing-based combat
Sonic Adventure 2: Battle
Speed-stage control and rail precision reward clean hands
Sonic Adventure 2: Battle leans a little harder on reads, though the gap is small.
Mirror's Edge Catalyst
Enemies are scripted obstacles
Sonic Adventure 2: Battle
Two-player battles exist but stay shallow and scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mirror's Edge Catalyst
Open world is static once explored
Sonic Adventure 2: Battle
Stages are fixed; Chao stats are deterministic grinding
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 Adventure 2: Battle
Rank chasing means memorising routes and score lines
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.
