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.

Execution · Practiced Mastery
A massive open-world sandbox built around grappling-hook and parachute chaos.
Euro Truck Simulator leans Optimization (Practiced Mastery); Just Cause 2 leans Execution (Practiced Mastery).
Just Cause 2 leans a little harder on execution, though the gap is small.
Euro Truck Simulator
Basic truck handling and parking
Just Cause 2
Grapple-parachute flow rewards handling skill
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
Just Cause 2
Enemy AI never adapts
Just Cause 2 leans a little harder on variance, though the gap is small.
Euro Truck Simulator
Minor traffic variation
Just Cause 2
Sandbox chaos varies moment to moment
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Euro Truck Simulator
Delivery routes and truck upgrades
Just Cause 2
Chaos-point economy and settlement completion 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.
