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
Managing scarce resources and learning authored scares that converge to routed runs.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Resident Evil Requiem leans Optimization (Practiced Mastery).
Resident Evil Requiem leans a little harder on execution, though the gap is small.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Resident Evil Requiem
Aiming under pressure matters but stays survivable
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
Resident Evil Requiem
Enemies and stalkers follow designed behaviour, not adaptive minds
Resident Evil Requiem leans a little harder on variance, though the gap is small.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Resident Evil Requiem
First-run horror trades on scripted-but-unknown encounters
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Resident Evil Requiem
Resource management and routing converge on optimal runs
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.
