head to head
Mortal Shell asks more than Grand Theft Auto: San Andreas, and the gap is execution.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.

Execution · Practiced Mastery
A lean souls-like carried by hardened-parry timing and shell selection.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Mortal Shell leans Execution (Practiced Mastery).
Mortal Shell leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Mortal Shell
Hardened parry timing demands inputs
Mortal Shell leans a little harder on reads, though the gap is small.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Mortal Shell
Scripted bosses
Grand Theft Auto: San Andreas leans a little harder on variance, though the gap is small.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Mortal Shell
Minor item randomness
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
Mortal Shell
Shell choice and upgrade routing matter
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.
