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
An open-city sequel deepening freeflow combat and predator gadget play.

Optimization · Practiced Mastery
Wasteland open-worlder upgrading one car to conquer scripted scrap territories.
Batman: Arkham City leans Execution (Practiced Mastery); Mad Max leans Optimization (Practiced Mastery).
Batman: Arkham City leans a little harder on execution, though the gap is small.
Batman: Arkham City
Combo chains and counters need timing.
Mad Max
Car combat and counter-brawling timing
Batman: Arkham City leans a little harder on reads, though the gap is small.
Batman: Arkham City
Enemies scripted, not adaptive.
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: Arkham City
Fixed encounters and challenges.
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: Arkham City
Gadget combos and challenge maps learnable.
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.
