head to head
Mirror's Edge Catalyst 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
Open-world reboot of Mirror's Edge centered on free-running across the city of Glass.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Mirror's Edge Catalyst leans Execution (Practiced Mastery).
Mirror's Edge Catalyst leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Mirror's Edge Catalyst
Flow-state parkour with timing-based combat
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
Mirror's Edge Catalyst
Enemies are scripted obstacles
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
Mirror's Edge Catalyst
Open world is static once explored
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
Mirror's Edge Catalyst
Time trials reward optimal route discovery
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.
