head to head
Grand Theft Auto V asks more than Zen Bound 2, and the gap is execution.

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

Optimization · Practiced Mastery
A meditative puzzle game about wrapping rope efficiently around 3D objects.
Grand Theft Auto V leans Execution (Practiced Mastery); Zen Bound 2 leans Optimization (Practiced Mastery).
Grand Theft Auto V leans clearly harder on execution.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Zen Bound 2
gentle rope-wrapping motion control
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Zen Bound 2
no opponent, meditative solo puzzle
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Zen Bound 2
physics settle slightly unpredictably
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto V
Heists, money loops, builds learnable.
Zen Bound 2
finding efficient wrap paths for coverage
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.
