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

Optimization · Practiced Mastery
A cinematic puzzle platformer about sneaking a hapless Mudokon past guards while rescuing his coworkers.

Optimization · Practiced Mastery
A forgiving platformer testing light execution and exploration routing through fixed level designs.
Oddworld: Abe's Oddysee leans Optimization (Practiced Mastery); Psychonauts 2 leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Oddworld: Abe's Oddysee
Precise platforming and stealth timing kill instantly
Psychonauts 2
Moderate platforming and combat timing, forgiving by design
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Oddworld: Abe's Oddysee
Sligs patrol on fixed scripts
Psychonauts 2
Solo adventure with no adaptive opponent anywhere
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Oddworld: Abe's Oddysee
Deterministic screens, no randomness
Psychonauts 2
Level layouts and collectibles are fixed once seen
Oddworld: Abe's Oddysee leans a little harder on optimization, though the gap is small.
Oddworld: Abe's Oddysee
Mudokon rescue routes and puzzle solutions are solvable
Psychonauts 2
Routing collectibles and matching psychic powers to encounters
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.
