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
A 2.5D platformer with deep user-created content.

Execution · Practiced Mastery
Light web-swinging execution over a scripted open-world checklist.
LittleBigPlanet 3 leans Execution (Practiced Mastery); Spider-Man 3 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.
LittleBigPlanet 3
Floaty platforming with varied character moves
Spider-Man 3
Swing control and combo timing carry the combat
LittleBigPlanet 3 leans a little harder on reads, though the gap is small.
LittleBigPlanet 3
Scripted enemies
Spider-Man 3
Enemies follow fixed scripts, nothing models you
LittleBigPlanet 3 leans a little harder on variance, though the gap is small.
LittleBigPlanet 3
User levels vary wildly
Spider-Man 3
Open-world missions are static once discovered
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
LittleBigPlanet 3
Costume and prize-bubble routing
Spider-Man 3
Upgrade paths and mission objectives are shallowly solvable
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.
