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
A comedic first-person exploration romp cataloguing a candy-coloured alien planet.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Journey to the Savage Planet leans Optimization (Practiced Mastery).
Grand Theft Auto: San Andreas leans a little harder on execution, though the gap is small.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Journey to the Savage Planet
Light shooting and platforming, forgiving
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
Journey to the Savage Planet
Creature AI is simple and scripted
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
Journey to the Savage Planet
Some unknown creature behaviours on first contact
Grand Theft Auto: San Andreas 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
Journey to the Savage Planet
Upgrade routing and scan-everything exploration
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.
