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

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

Execution · Practiced Mastery
Splitting attention between hacking puzzles and gunplay against patterned machines.
Grand Theft Auto V leans Execution (Practiced Mastery); Pragmata leans Execution (Practiced Mastery).
Pragmata leans clearly harder on execution.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Pragmata
Juggling real-time hacking minigames while shooting demands coordination
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Pragmata
Robotic enemies follow designed patterns, not adaptation
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Pragmata
Authored sci-fi campaign with little randomness
Pragmata leans clearly harder on optimization.
Grand Theft Auto V
Heists, money loops, builds learnable.
Pragmata
Sequencing hack-then-shoot solutions per enemy is the puzzle
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.
