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 cinematic action game about Senua's journey through Norse hell.

Execution · Practiced Mastery
Cinematic treasure-hunting where set pieces outshine systems.
Hellblade: Senua's Sacrifice 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.
Hellblade: Senua's Sacrifice
Combat parries and dodges need timing.
Uncharted 4: A Thief's End
Cover shooting and platforming reward timing.
Uncharted 4: A Thief's End leans a little harder on reads, though the gap is small.
Hellblade: Senua's Sacrifice
Bosses are scripted.
Uncharted 4: A Thief's End
Scripted enemy AI throughout.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Hellblade: Senua's Sacrifice
Minimal randomness.
Uncharted 4: A Thief's End
Essentially no randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Hellblade: Senua's Sacrifice
Few build systems.
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.
