head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Practiced Mastery
Open-world western about an outlaw forced to hunt down his old gang.

Execution · Practiced Mastery
An open-world co-op shooter testing moderate aim and loot-driven build progression.
Red Dead Redemption leans Execution (Practiced Mastery); Redfall 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.
Red Dead Redemption
Dead Eye softens but gunplay still wants aim
Redfall
Standard FPS gunplay with forgiving co-op margins
Red Dead Redemption leans a little harder on reads, though the gap is small.
Red Dead Redemption
Multiplayer skirmishes add light human prediction
Redfall
Vampires and cultists run predictable AI scripts
Redfall leans a little harder on variance, though the gap is small.
Red Dead Redemption
Ambient events and spawns vary mildly
Redfall
Loot rolls and open-world spawns add randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption
Mission approaches and economy are learnable
Redfall
Hero builds and weapon tiers form a modest progression puzzle
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.
