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 mechanically demanding action RPG where parry timing and echo build optimisation define endgame performance.
Demon's Souls leans Execution (Practiced Mastery); Wuthering Waves leans Execution (Practiced Mastery).
Wuthering Waves leans a little harder on execution, though the gap is small.
Demon's Souls
Stamina-timed dodges and parries punish sloppy hands.
Wuthering Waves
Perfect dodges, Parry timing, and echo cancels are load-bearing
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.
Wuthering Waves
PvE only; no adaptive human opponent to model
Wuthering Waves leans a little harder on variance, though the gap is small.
Demon's Souls
World tendency and upgrade drops add mild noise.
Wuthering Waves
Gacha pulls and echo substat RNG introduce meaningful hidden 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.
Wuthering Waves
Resonator builds and echo set synergies are deeply theory-crafted
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.
