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

Optimization · Pure Optimization
American trucking sim about long hauls and growth.

Optimization · Practiced Mastery
An open-world crime game where managing a criminal empire's territory is the deeper system.
American Truck Simulator leans Optimization (Pure Optimization); The Godfather II leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
American Truck Simulator
Truck handling and trailer parking
The Godfather II
shooting and brawling need moderate skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
American Truck Simulator
No adaptive opponents
The Godfather II
scripted rival families, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
American Truck Simulator
Traffic and weather variance
The Godfather II
territory events and drops vary
American Truck Simulator leans a little harder on optimization, though the gap is small.
American Truck Simulator
Fleet, garages, route economics
The Godfather II
empire management and territory control solvable
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.
