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

Sandbox crime playground spanning shooting, driving, and a persistent online economy.

Choreographing your real body through plannable frozen-time combat puzzles.
Grand Theft Auto V leans Execution (Practiced Mastery); SuperHot VR leans Execution (Practiced Mastery).
SuperHot VR leans clearly harder on execution.
Grand Theft Auto V
Driving and shooting demand decent inputs.
SuperHot VR
Physical dodging, grabbing and aiming with your actual body
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
SuperHot VR
Enemies follow fixed spawn patterns, never adapting
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
SuperHot VR
Scenarios replay identically once learned
SuperHot VR leans clearly harder on optimization.
Grand Theft Auto V
Heists, money loops, builds learnable.
SuperHot VR
Planning movement sequences through frozen time is a solvable puzzle
