head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Practiced Mastery
Following authored stealth-fear sequences with learnable intended solutions.

Optimization · Practiced Mastery
Wasteland open-worlder upgrading one car to conquer scripted scrap territories.
Batman Begins leans Optimization (Practiced Mastery); Mad Max leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Batman Begins
Combat and stealth inputs are forgiving
Mad Max
Car combat and counter-brawling timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Batman Begins
Guards follow scripted fear and patrol patterns
Mad Max
War boys follow fixed AI
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Batman Begins
Encounters are staged identically every run
Mad Max
Open world is static once scouted
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Batman Begins
Each fear-scripted sequence has an intended solution to find
Mad Max
Magnum Opus upgrades and stronghold routing
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.
