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.

Execution · Practiced Mastery
Superhero sequel adding melee combat and a karma-split power arsenal in New Marais.

Execution · Practiced Mastery
A scripted action romp testing combat timing and memorised boss patterns.
inFamous 2 leans Execution (Practiced Mastery); Spider-Man: Shattered Dimensions 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.
inFamous 2
Faster combat with melee and aimed powers
Spider-Man: Shattered Dimensions
Combo timing and traversal demand moderate hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
inFamous 2
Scripted enemy factions, no adaptation
Spider-Man: Shattered Dimensions
Bosses and enemies are fully scripted, never adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
inFamous 2
Static world, fixed encounters
Spider-Man: Shattered Dimensions
Linear levels with almost nothing hidden or random
inFamous 2 leans a little harder on optimization, though the gap is small.
inFamous 2
Karma-gated power trees shape the run
Spider-Man: Shattered Dimensions
Upgrade choices and learning boss patterns carry the rest
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.
