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.

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

Optimization · Pure Optimization
An invincible Wario solves transformation puzzles to reclaim treasures inside a cursed music box.
Oddworld: Abe's Oddysee leans Optimization (Practiced Mastery); Wario Land 3 leans Optimization (Pure Optimization).
Oddworld: Abe's Oddysee leans a little harder on execution, though the gap is small.
Oddworld: Abe's Oddysee
Precise platforming and stealth timing kill instantly
Wario Land 3
Invincible Wario shifts weight off reflexes
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
Wario Land 3
No adaptive opponents
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
Wario Land 3
Treasure effects unknown on first discovery
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Oddworld: Abe's Oddysee
Mudokon rescue routes and puzzle solutions are solvable
Wario Land 3
Transformation puzzles and treasure unlock order are the game
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.
