head to head
M.U.S.H.A. 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
Compile's mecha vertical shmup for the Genesis, famed for speed and configurable option pods.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); M.U.S.H.A. leans Execution (Practiced Mastery).
M.U.S.H.A. leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
M.U.S.H.A.
Fast vertical dodging through dense fire tests the hands.
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
M.U.S.H.A.
Enemies follow fixed choreography.
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
M.U.S.H.A.
Stages are fixed and memorisable.
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
M.U.S.H.A.
Option formations and weapon choice reward system mastery.
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.
