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
A Himalayan open-world shooter refining the outpost-clearing formula.

Optimization · Practiced Mastery
Series finale blending stealth with active battlefields and heavy cinematics.
Far Cry 4 leans Execution (Practiced Mastery); Metal Gear Solid 4: Guns of the Patriots leans Optimization (Practiced Mastery).
Far Cry 4 leans a little harder on execution, though the gap is small.
Far Cry 4
Gunplay plus gyrocopter and elephant chaos
Metal Gear Solid 4: Guns of the Patriots
flexible gunplay alongside sneaking
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Far Cry 4
Scripted outpost AI
Metal Gear Solid 4: Guns of the Patriots
battlefield factions act on scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Far Cry 4
Wildlife and patrol variation
Metal Gear Solid 4: Guns of the Patriots
mid-battle chaos mostly cosmetic
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Far Cry 4
Outpost approaches and skill trees are plannable
Metal Gear Solid 4: Guns of the Patriots
camo, gear, and route knowledge per act
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.
