head to head
Doom: The Dark Ages asks more than Grand Theft Auto: San Andreas, and the gap is execution.

Execution · Practiced Mastery
A medieval-flavored Doom prequel built around shield parries and heavy combat.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Doom: The Dark Ages leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
Doom: The Dark Ages leans clearly harder on execution.
Doom: The Dark Ages
Parry timing and shield play demand precise 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.
Doom: The Dark Ages
Demon attack patterns are fixed and learnable
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.
Doom: The Dark Ages
Encounters fully scripted
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.
Doom: The Dark Ages
Upgrade paths and combat-loop mastery solve fights
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.
