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
The original European trucking sim of long hauls and tidy deliveries.

Optimization · Practiced Mastery
Wasteland open-worlder upgrading one car to conquer scripted scrap territories.
Euro Truck Simulator leans Optimization (Practiced Mastery); Mad Max leans Optimization (Practiced Mastery).
Mad Max leans a little harder on execution, though the gap is small.
Euro Truck Simulator
Basic truck handling and parking
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.
Euro Truck Simulator
No adaptive opposition
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.
Euro Truck Simulator
Minor traffic variation
Mad Max
Open world is static once scouted
Mad Max leans a little harder on optimization, though the gap is small.
Euro Truck Simulator
Delivery routes and truck upgrades
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.
