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
An open-world chaos sandbox adding tornado weather to grappling-hook anarchy.

Execution · Practiced Mastery
Open-world superhero game whose joy is fluid web-swinging and rhythmic combat.
Just Cause 4 leans Execution (Practiced Mastery); Marvel's Spider-Man leans Execution (Practiced Mastery).
Marvel's Spider-Man leans a little harder on execution, though the gap is small.
Just Cause 4
Wingsuit and customised tether handling
Marvel's Spider-Man
swinging flow and combat dodge timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Just Cause 4
Enemy AI is static
Marvel's Spider-Man
thugs and bosses follow fixed patterns
Just Cause 4 leans a little harder on variance, though the gap is small.
Just Cause 4
Weather fronts shake encounters up slightly
Marvel's Spider-Man
open world is fully discoverable
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Just Cause 4
Frontline progression and loadout tinkering
Marvel's Spider-Man
gadget loadouts and suit mods are shallow but present
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.
