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

Execution · Practiced Mastery
A fast falling-block puzzle testing speed placement and chain planning.
Far Cry Primal leans Execution (Practiced Mastery); Raining Blobs leans Execution (Practiced Mastery).
Raining Blobs leans a little harder on execution, though the gap is small.
Far Cry Primal
Bow aim, melee timing, beast control under pressure
Raining Blobs
Fast block placement under accelerating speed decides runs
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
Raining Blobs
Optional versus but mostly solo, little prediction
Raining Blobs leans a little harder on variance, though the gap is small.
Far Cry Primal
Wildlife encounters and patrol spawns are random
Raining Blobs
Falling blob colors are random but quickly mappable
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Far Cry Primal
Outpost routes, crafting economy, beast taming order
Raining Blobs
Chaining and clearing patterns has known optimal play
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.
