head to head
Grand Theft Auto V asks more than Super Mario Bros. Wonder, and the gap is reads.

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

Execution · Practiced Mastery
Approachable precision platforming through authored levels full of one-time surprises.
Grand Theft Auto V leans Execution (Practiced Mastery); Super Mario Bros. Wonder leans Execution (Practiced Mastery).
Super Mario Bros. Wonder leans a little harder on execution, though the gap is small.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Super Mario Bros. Wonder
Precise jumps and badge tricks are the skill test
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Super Mario Bros. Wonder
Enemies follow classic fixed patterns
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Super Mario Bros. Wonder
Wonder effects surprise once, then are known
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.
Super Mario Bros. Wonder
Collectible routes and badge choices are lightly solvable
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.
