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 co-op looter shooter where aggressive ability builds and gear mods carry you through escalating expeditions.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Outriders leans Optimization (Practiced Mastery).
Outriders leans a little harder on execution, though the gap is small.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Outriders
Cover shooting and ability timing matter
Outriders leans a little harder on reads, though the gap is small.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Outriders
AI hordes are scripted aggression
Outriders leans a little harder on variance, though the gap is small.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Outriders
Loot rolls gate the build chase
Outriders 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
Outriders
Class builds and mod stacking dominate endgame
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.
