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 · Pure Optimization
Co-op LEGO brawler where unlocking the right character to grab every collectible is the game.

Optimization · Practiced Mastery
A slow life-sim adventure testing patience, daily routines and light combat.
LEGO Batman: The Videogame leans Optimization (Pure Optimization); Shenmue III leans Optimization (Practiced Mastery).
Shenmue III leans a little harder on execution, though the gap is small.
LEGO Batman: The Videogame
Button-mashy combat with no real fail state
Shenmue III
Light fighting timing and QTEs, mostly forgiving
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
LEGO Batman: The Videogame
Scripted goons and bosses
Shenmue III
Sparring AI is scripted, never models you
Shenmue III leans a little harder on variance, though the gap is small.
LEGO Batman: The Videogame
Stud and brick locations fixed
Shenmue III
Where clues and gambling odds land is mildly random
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
LEGO Batman: The Videogame
Character-ability gating drives collectible completion
Shenmue III
Money routines, training grind and clue routing structure the days
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.
