head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Practiced Mastery
Sequel refining the fast rabbit platforming with co-op and multiplayer modes.

Execution · Practiced Mastery
Moderate platforming execution through inventive but fixed mental levels.
Jazz Jackrabbit 2 leans Execution (Practiced Mastery); Psychonauts 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.
Jazz Jackrabbit 2
Fast movement, ammo juggling, tight jumps
Psychonauts
Platforming and psychic combat need moderate precision
Jazz Jackrabbit 2 leans a little harder on reads, though the gap is small.
Jazz Jackrabbit 2
Mainly scripted; light multiplayer modes existed
Psychonauts
Mental-world enemies follow fixed behaviours
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Jazz Jackrabbit 2
Deterministic levels
Psychonauts
Level layouts are fixed and quickly known
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Jazz Jackrabbit 2
Weapon choice and secret routes
Psychonauts
Collectible routing and power upgrades add light planning
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.
