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
A post-apocalyptic Far Cry spinoff adding light RPG tiers to outpost raids.

Execution · Practiced Mastery
Gothic PS1 action horror of brutal melee against Victorian monsters.
Far Cry New Dawn leans Execution (Practiced Mastery); Nightmare Creatures 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.
Far Cry New Dawn
Standard Far Cry gunplay
Nightmare Creatures
Combo timing and dodges against tough monsters
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Far Cry New Dawn
Scripted raider AI
Nightmare Creatures
Creatures use fixed attack patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Far Cry New Dawn
Expedition loot rolls
Nightmare Creatures
Ambush placement unknown first time through
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Far Cry New Dawn
Outpost escalation and light RPG gear tiers
Nightmare Creatures
Adrenaline meter management and route learning
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.
