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.

Optimization · Practiced Mastery
Co-op first-person zombie RPG about improvised weapons on a resort island.

Execution · Practiced Mastery
A gritty African shooter where systemic chaos roughens every firefight.
Dead Island leans Optimization (Practiced Mastery); Far Cry 2 leans Execution (Practiced Mastery).
Far Cry 2 leans a little harder on execution, though the gap is small.
Dead Island
first-person melee timing and stamina
Far Cry 2
Gunplay with degrading, jamming weapons
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Island
zombies are scripted swarms
Far Cry 2
Mercenary AI is mappable
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Island
weapon drops and spawns add noise
Far Cry 2
Malaria, jams, and fire spread inject chaos
Dead Island leans a little harder on optimization, though the gap is small.
Dead Island
weapon mods and skill builds carry late game
Far Cry 2
Loadout and route planning across hostile terrain
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.
