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
A driving sim testing smooth vehicle handling against timetables and traffic rules.

Optimization · Practiced Mastery
An open-world crime game where managing a criminal empire's territory is the deeper system.
Bus Driver leans Optimization (Practiced Mastery); 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.
Bus Driver
Smooth braking and lane discipline are the physical test
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.
Bus Driver
Traffic follows predictable scripted rules
The Godfather II
scripted rival families, no adaptation
The Godfather II leans a little harder on variance, though the gap is small.
Bus Driver
Routes and conditions are set per scenario
The Godfather II
territory events and drops vary
The Godfather II leans a little harder on optimization, though the gap is small.
Bus Driver
Timetable adherence and rule-following decide the score
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.
