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
The original Souls game: scripted boss patterns you solve with builds, routes and disciplined execution.

Execution · Practiced Mastery
A brutally resource-scarce survival game that rewards upgrade planning and precise gunplay equally.
Demon's Souls leans Execution (Practiced Mastery); The Evil Within 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.
Demon's Souls
Stamina-timed dodges and parries punish sloppy hands.
The Evil Within
Precise shooting and crafting under scarce resources demand execution
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Demon's Souls
Invasions exist but bosses are scripted patterns.
The Evil Within
Haunted follow fixed behaviours; Ruvik is a scripted trigger
The Evil Within leans a little harder on variance, though the gap is small.
Demon's Souls
World tendency and upgrade drops add mild noise.
The Evil Within
Chest contents and drop tables have minor variance
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Demon's Souls
Builds, routes and learned movesets are fully solvable.
The Evil Within
Upgrade tree, bottle routing and enemy-avoid sequencing are deeply optimisable
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.
