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
Moderate platforming execution through inventive but fixed mental levels.

Execution · Pure Mechanics
An auto-runner spinoff of Sonic testing quick reflexes and route memorization.
Psychonauts leans Execution (Practiced Mastery); Sonic Runners leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Psychonauts
Platforming and psychic combat need moderate precision
Sonic Runners
timing jumps/dashes at speed rewards precise inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Psychonauts
Mental-world enemies follow fixed behaviours
Sonic Runners
no opponent to out-predict, pure solo runner
Sonic Runners leans a little harder on variance, though the gap is small.
Psychonauts
Level layouts are fixed and quickly known
Sonic Runners
occasional random item drops and obstacle layout
Psychonauts leans a little harder on optimization, though the gap is small.
Psychonauts
Collectible routing and power upgrades add light planning
Sonic Runners
route/lane and upgrade optimization for score
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.
