head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
Moderate platforming execution through inventive but fixed mental levels.

Execution · Practiced Mastery
Positioning and attack timing against memorisable enemy waves, built to eat quarters.
Psychonauts leans Execution (Practiced Mastery); Teenage Mutant Ninja Turtles 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.
Psychonauts
Platforming and psychic combat need moderate precision
Teenage Mutant Ninja Turtles
Crowd control timing and positioning against waves is everything
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
Teenage Mutant Ninja Turtles
Color-coded Foot Soldiers follow fixed attack patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Psychonauts
Level layouts are fixed and quickly known
Teenage Mutant Ninja Turtles
Spawns are scripted and identical every credit
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Psychonauts
Collectible routing and power upgrades add light planning
Teenage Mutant Ninja Turtles
Learning safe spots and boss patterns stretches each quarter
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.
