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 superhero game whose joy is fluid web-swinging and rhythmic combat.

Execution · Practiced Mastery
Cinematic treasure-hunting where set pieces outshine systems.
Marvel's Spider-Man leans Execution (Practiced Mastery); Uncharted 4: A Thief's End 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.
Marvel's Spider-Man
swinging flow and combat dodge timing
Uncharted 4: A Thief's End
Cover shooting and platforming reward timing.
Uncharted 4: A Thief's End leans a little harder on reads, though the gap is small.
Marvel's Spider-Man
thugs and bosses follow fixed patterns
Uncharted 4: A Thief's End
Scripted enemy AI throughout.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Marvel's Spider-Man
open world is fully discoverable
Uncharted 4: A Thief's End
Essentially no randomness.
Marvel's Spider-Man leans a little harder on optimization, though the gap is small.
Marvel's Spider-Man
gadget loadouts and suit mods are shallow but present
Uncharted 4: A Thief's End
Few systems to optimize beyond difficulty.
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.
