head to head
Neither is simply harder - they are hard in different places. Grand Theft Auto V demands more reads; Shadow Warrior 2 demands more execution.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.

Execution · Practiced Mastery
A loot-driven action shooter combining precise combat execution with deep weapon-crafting optimisation.
Grand Theft Auto V leans Execution (Practiced Mastery); Shadow Warrior 2 leans Execution (Practiced Mastery).
Shadow Warrior 2 leans clearly harder on execution.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Shadow Warrior 2
Fast melee and gun chains demand sustained precise input execution
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Shadow Warrior 2
All enemies are scripted; no adaptive opponent present
Shadow Warrior 2 leans clearly harder on variance.
Grand Theft Auto V
Some mission and lobby randomness.
Shadow Warrior 2
Loot drops and procedural mission modifiers introduce meaningful variance
Shadow Warrior 2 leans clearly harder on optimization.
Grand Theft Auto V
Heists, money loops, builds learnable.
Shadow Warrior 2
Weapon modding and skill build optimisation form a deep solvable layer
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.
