head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
Physical, grapple-heavy combat against learnable boss movesets in an open world.
Execution · Practiced Mastery
A maze shooter about navigating a tomb, collecting keys and dodging creatures.
Crimson Desert leans Execution (Practiced Mastery); Tutankham 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.
Crimson Desert
Grapple-heavy combat timing and combos demand active hands
Tutankham
Shooting horizontally and dodging creatures needs reflexes
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Crimson Desert
Bosses telegraph fixed movesets, no adaptation
Tutankham
Creatures are scripted, not adaptive opponents
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crimson Desert
Open-world encounters add mild discovery randomness
Tutankham
Enemy spawns add minor unpredictability
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Crimson Desert
Learning boss patterns and gear progression drives mastery
Tutankham
Memorizing maze layouts and key routes is essential
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.
