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 Metroidvania roguelite blending precise combat with procedural exploration.
Demon's Souls leans Execution (Practiced Mastery); Sundered: Eldritch Edition 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.
Sundered: Eldritch Edition
precise platforming and combat dodges
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.
Sundered: Eldritch Edition
enemies swarm but don't adapt to player
Sundered: Eldritch Edition leans a little harder on variance, though the gap is small.
Demon's Souls
World tendency and upgrade drops add mild noise.
Sundered: Eldritch Edition
procedural level layouts and item rolls
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.
Sundered: Eldritch Edition
skill tree corruption choices, build paths
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.
