head to head
Bloodstained: Curse of the Moon asks more than Grand Theft Auto: San Andreas, and the gap is execution.

Execution · Practiced Mastery
Deliberate retro platform execution with character-swap route planning.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Bloodstained: Curse of the Moon leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
Bloodstained: Curse of the Moon leans clearly harder on execution.
Bloodstained: Curse of the Moon
Stiff retro jumps and boss dodges demand committed inputs
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.
Bloodstained: Curse of the Moon
Bosses telegraph from strictly fixed scripts
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Grand Theft Auto: San Andreas leans a little harder on variance, though the gap is small.
Bloodstained: Curse of the Moon
Levels are deterministic on every run
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Grand Theft Auto: San Andreas leans a little harder on optimization, though the gap is small.
Bloodstained: Curse of the Moon
Character-swap routing and branch choices reward planning
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.
