head to head
Grand Theft Auto V asks more than Super Mario 3D Land, and the gap is reads.

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

Execution · Practiced Mastery
A bite-sized 3D Mario that compresses Galaxy-style level design into linear handheld courses.
Grand Theft Auto V leans Execution (Practiced Mastery); Super Mario 3D Land leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Super Mario 3D Land
3D jumps and special-world remixes need clean control
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Super Mario 3D Land
Scripted enemies and bosses only
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 3D Land
Star coin locations hidden on first pass
Super Mario 3D Land leans a little harder on optimization, though the gap is small.
Grand Theft Auto V
Heists, money loops, builds learnable.
Super Mario 3D Land
Star coin collection and power-up management are 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.
