head to head
Grand Theft Auto V asks more than Human: Fall Flat, and the gap is reads.

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

Slapstick physics puzzler about hauling a wobbly ragdoll through dreamscapes.
Grand Theft Auto V leans Execution (Practiced Mastery); Human: Fall Flat leans Optimization (Practiced Mastery).
Grand Theft Auto V leans a little harder on execution, though the gap is small.

Human: Fall Flat

Grand Theft Auto V
Heists, money loops, builds learnable.
Human: Fall Flat
Puzzle solutions and shortcut discovery
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.
