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
The black-sheep sequel whose passive enemies and dominant guns sand the series' skill ceiling way down.

Optimization · Practiced Mastery
Wasteland open-worlder upgrading one car to conquer scripted scrap territories.
Devil May Cry 2 leans Execution (Practiced Mastery); Mad Max leans Optimization (Practiced Mastery).
Devil May Cry 2 leans a little harder on execution, though the gap is small.
Devil May Cry 2
Infamously easy; guns trivialize most encounters
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.
Devil May Cry 2
Passive enemy AI never pressures, let alone adapts
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.
Devil May Cry 2
Flat authored levels hide little
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.
Devil May Cry 2
Amulet builds and boss patterns fall fast
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.
