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
A sprawling open-world crime epic with RPG-style character stats across a whole state.

Optimization · Practiced Mastery
An off-road hauling simulator about planning routes and nursing heavy trucks through mud, ice and rivers.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); SnowRunner leans Optimization (Practiced Mastery).
SnowRunner leans a little harder on execution, though the gap is small.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
SnowRunner
Throttle finesse and winch work prevent disasters.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
SnowRunner
No opponents; terrain is the only adversary.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
SnowRunner
Mud and ice physics surprise until terrain is learned.
SnowRunner leans a little harder on optimization, though the gap is small.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
SnowRunner
Truck loadouts, route planning and fuel logistics decide deliveries.
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.
