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
Open-world Stone Age action game about hunting and conquering tribal outposts with tamed beasts.

Execution · Practiced Mastery
A top-down co-op shooter testing aim and upgrade optimization against alien swarms.
Far Cry Primal leans Execution (Practiced Mastery); From Space 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 Primal
Bow aim, melee timing, beast control under pressure
From Space
Twin-stick aiming and dodging swarms is core
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Far Cry Primal
Scripted tribal AI never models the player
From Space
Aliens are scripted/random, not adaptive minds
From Space leans a little harder on variance, though the gap is small.
Far Cry Primal
Wildlife encounters and patrol spawns are random
From Space
Random spawns and drops add chaos
From Space leans a little harder on optimization, though the gap is small.
Far Cry Primal
Outpost routes, crafting economy, beast taming order
From Space
Weapon upgrades and squad coordination reward 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.
