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
Wasteland open-worlder upgrading one car to conquer scripted scrap territories.

Optimization · Practiced Mastery
A slow life-sim adventure testing patience, daily routines and light combat.
Mad Max leans Optimization (Practiced Mastery); Shenmue III leans Optimization (Practiced Mastery).
Mad Max leans a little harder on execution, though the gap is small.
Mad Max
Car combat and counter-brawling timing
Shenmue III
Light fighting timing and QTEs, mostly forgiving
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mad Max
War boys follow fixed AI
Shenmue III
Sparring AI is scripted, never models you
Shenmue III leans a little harder on variance, though the gap is small.
Mad Max
Open world is static once scouted
Shenmue III
Where clues and gambling odds land is mildly random
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mad Max
Magnum Opus upgrades and stronghold routing
Shenmue III
Money routines, training grind and clue routing structure the days
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.
