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
A sprawling open-world crime epic with RPG-style character stats across a whole state.

Execution · Practiced Mastery
A WWII shooter taking a Marine through the Pacific island campaign.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Medal of Honor: Pacific Assault leans Execution (Practiced Mastery).
Medal of Honor: Pacific Assault leans a little harder on execution, though the gap is small.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Medal of Honor: Pacific Assault
Recoil-heavy gunplay in jungle firefights
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Medal of Honor: Pacific Assault
Squad and enemy AI follow scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Medal of Honor: Pacific Assault
Jungle ambushes surprise only first time
Grand Theft Auto: San Andreas leans a little harder on optimization, though the gap is small.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Medal of Honor: Pacific Assault
Health-medic economy and routes are learnable
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.
