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.

Optimization · Practiced Mastery
The original loot-driven co-op shooter set on the bandit world of Pandora.

Execution · Practiced Mastery
An open-world co-op shooter testing moderate aim and loot-driven build progression.
Borderlands leans Optimization (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.
Borderlands
Standard FPS aim; numbers matter more than precision
Redfall
Standard FPS gunplay with forgiving co-op margins
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Borderlands
Bandits and skags are scripted
Redfall
Vampires and cultists run predictable AI scripts
Borderlands leans a little harder on variance, though the gap is small.
Borderlands
Procedural loot drops gate your power
Redfall
Loot rolls and open-world spawns add randomness
Borderlands leans a little harder on optimization, though the gap is small.
Borderlands
Builds, gear math, and farming routes dominate
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.
