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
First-person melee timing against scripted hordes, supported by a craftable weapon economy.

Execution · Practiced Mastery
Story-driven action adventure carried by its banter more than its combat depth.
Dead Island 2 leans Execution (Practiced Mastery); Marvel's Guardians of the Galaxy leans Execution (Practiced Mastery).
Dead Island 2 leans a little harder on execution, though the gap is small.
Dead Island 2
Melee timing, dodges and zombie crowd control need decent hands
Marvel's Guardians of the Galaxy
third-person shooting with generous checkpoints
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Island 2
Zombies follow scripted aggression patterns, never model you
Marvel's Guardians of the Galaxy
enemies follow fixed behaviors
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Island 2
Loot drops and zombie spawns add mild run-to-run noise
Marvel's Guardians of the Galaxy
story beats unknown only on first playthrough
Dead Island 2 leans a little harder on optimization, though the gap is small.
Dead Island 2
Weapon mods, skill cards and elemental matchups reward planning
Marvel's Guardians of the Galaxy
ability priorities and huddle timing are light systems
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.
