head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Execution · Practiced Mastery
A narrative third-person shooter that turns a Dubai rescue mission into a study of war's moral cost.

Execution · Practiced Mastery
Cinematic treasure-hunting where set pieces outshine systems.
Spec Ops: The Line leans Execution (Practiced Mastery); Uncharted 4: A Thief's End 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.
Spec Ops: The Line
Competent cover shooting is all the game demands
Uncharted 4: A Thief's End
Cover shooting and platforming reward timing.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Spec Ops: The Line
Enemy squads follow fixed scripted assaults
Uncharted 4: A Thief's End
Scripted enemy AI throughout.
Spec Ops: The Line leans a little harder on variance, though the gap is small.
Spec Ops: The Line
Set-piece encounters play out the same each run
Uncharted 4: A Thief's End
Essentially no randomness.
Spec Ops: The Line leans a little harder on optimization, though the gap is small.
Spec Ops: The Line
Cover routes and loadout choices are quickly solved
Uncharted 4: A Thief's End
Few systems to optimize beyond difficulty.
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.
