head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Optimization · Practiced Mastery
Wasteland open-worlder upgrading one car to conquer scripted scrap territories.

Execution · Practiced Mastery
Tests casual open-world chaos appetite more than any skill axis.
Mad Max leans Optimization (Practiced Mastery); Saints Row leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Mad Max
Car combat and counter-brawling timing
Saints Row
Forgiving shooting and driving demand little precision
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
Saints Row
Gang AI runs simple fixed scripts
Saints Row leans a little harder on variance, though the gap is small.
Mad Max
Open world is static once scouted
Saints Row
Open-world events vary mildly between sessions
Mad Max leans a little harder on optimization, though the gap is small.
Mad Max
Magnum Opus upgrades and stronghold routing
Saints Row
Perks, weapons and venture economy reward light planning
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.
