head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
A PS2 driving simulator centred on mastering tracks and tuning cars through events.

Execution · Practiced Mastery
NES boxing game built entirely on memorizing opponent tells and executing split-second counters.
Gran Turismo 3: A-Spec leans Execution (Practiced Mastery); Mike Tyson's Punch-Out!! 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.
Gran Turismo 3: A-Spec
Lap precision against the clock is the core test
Mike Tyson's Punch-Out!!
Frame-tight dodges and counters, brutal at Tyson
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Gran Turismo 3: A-Spec
AI opponents never adapt
Mike Tyson's Punch-Out!!
Every boxer follows fixed tells and patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Gran Turismo 3: A-Spec
Deterministic physics, minimal randomness
Mike Tyson's Punch-Out!!
Almost fully deterministic once patterns are known
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Gran Turismo 3: A-Spec
Optimal cars, tunes, and racing lines are findable
Mike Tyson's Punch-Out!!
Memorizing each opponent's pattern is half the game
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.
