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.

Execution · Practiced Mastery
An open-world co-op shooter testing moderate aim and loot-driven build progression.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Redfall leans Execution (Practiced Mastery).
Redfall leans a little harder on execution, though the gap is small.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Redfall
Standard FPS gunplay with forgiving co-op margins
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
Redfall
Vampires and cultists run predictable AI scripts
Redfall leans a little harder on variance, though the gap is small.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Redfall
Loot rolls and open-world spawns add randomness
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
Redfall
Hero builds and weapon tiers form a modest progression puzzle
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.
