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.

Execution · Practiced Mastery
A licensed platformer testing basic jump timing and level memorisation.

Execution · Practiced Mastery
A family-friendly 3D platformer with co-op stages.
Disney's Tarzan leans Execution (Practiced Mastery); Sackboy: A Big Adventure leans Execution (Practiced Mastery).
Disney's Tarzan leans a little harder on execution, though the gap is small.
Disney's Tarzan
Jump timing and projectile tossing carry the platforming
Sackboy: A Big Adventure
Light 3D platforming, some co-op timing
Sackboy: A Big Adventure leans a little harder on reads, though the gap is small.
Disney's Tarzan
Jungle enemies run fixed simple patterns
Sackboy: A Big Adventure
Scripted enemies
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Disney's Tarzan
Collectible placements fixed; nothing meaningfully random
Sackboy: A Big Adventure
Static levels
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Disney's Tarzan
Memorising level layouts and letter locations completes it
Sackboy: A Big Adventure
Collectible and costume hunting
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.
