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

Execution · Practiced Mastery
A stylish action game demanding sharp execution through layered combo and dodge timing while optimising chip builds around fixed enemy choreography.
Demon's Souls leans Execution (Practiced Mastery); Nier: Automata leans Execution (Practiced Mastery).
Nier: Automata leans a little harder on execution, though the gap is small.
Demon's Souls
Stamina-timed dodges and parries punish sloppy hands.
Nier: Automata
Fast combos, dodge timing, and bullet-hell patterns demand precise inputs
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.
Nier: Automata
Enemies follow scripted patterns; no adaptive opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Demon's Souls
World tendency and upgrade drops add mild noise.
Nier: Automata
Loot drops and chip rolls add minor randomness to builds
Demon's Souls leans a little harder on optimization, though the gap is small.
Demon's Souls
Builds, routes and learned movesets are fully solvable.
Nier: Automata
Chip loadout, weapon choice, and attack routing reward systematic planning
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.
