head to head
Kingdom Come: Deliverance 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 grounded medieval RPG where sword timing and skill planning both matter.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Kingdom Come: Deliverance leans Execution (Practiced Mastery).
Kingdom Come: Deliverance leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Kingdom Come: Deliverance
Directional sword combat, real timing needed
Kingdom Come: Deliverance leans clearly harder on reads.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Kingdom Come: Deliverance
Enemy AI somewhat reactive in duels
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Kingdom Come: Deliverance
Skill checks and durability rolls
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
Kingdom Come: Deliverance
Skill trees, alchemy, gear upkeep planning
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.
