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

Execution · Practiced Mastery
A physics-driven VR shooter where every object and fight obeys simulated weight.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.
Boneworks leans Execution (Practiced Mastery); Grand Theft Auto V leans Execution (Practiced Mastery).
Boneworks leans clearly harder on execution.
Boneworks
Full-physics VR aiming, climbing, and melee demand body control
Grand Theft Auto V
Driving and shooting demand decent inputs.
Grand Theft Auto V leans clearly harder on reads.
Boneworks
Enemies are simple scripted AI
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Boneworks
Physics jank adds noise, not hidden information
Grand Theft Auto V
Some mission and lobby randomness.
Boneworks leans a little harder on optimization, though the gap is small.
Boneworks
Puzzle solutions and item routes are fixed
Grand Theft Auto V
Heists, money loops, builds learnable.
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.
