head to head
Spider-Man: Web of Shadows 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
An open-world superhero brawler where Spider-Man swaps suits mid-combo during a symbiote invasion of Manhattan.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Spider-Man: Web of Shadows leans Execution (Practiced Mastery).
Spider-Man: Web of Shadows leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Spider-Man: Web of Shadows
Air combos and web-strike chains reward fast hands

Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Spider-Man: Web of Shadows
Symbiote hordes attack on fixed scripts
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
Spider-Man: Web of Shadows
City events are predictable filler
Grand Theft Auto: San Andreas leans a little harder on optimization, though the gap is small.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Spider-Man: Web of Shadows
Red-versus-black suit choice and upgrade paths are solvable
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.
