head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Optimization · Practiced Mastery
Solving fixed environmental puzzles by trial and error, with light timed stealth.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Black the Fall leans Optimization (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Black the Fall
Some timed stealth and chase sections demand light precision
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Black the Fall
Guards and machines run fixed detection scripts
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Black the Fall leans a little harder on variance, though the gap is small.
Black the Fall
Puzzle mechanics are unknown until each trial-and-error death
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Black the Fall
Each room is a fixed puzzle with one solution
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
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.
