EA's Frostbite-powered golf game mixing swing timing with course-management decisions.

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Black Mesa
Classic FPS aim and platforming sequences
Rory McIlroy PGA Tour
Swing timing and putt pace are the physical test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Minor enemy placement surprises first run
Rory McIlroy PGA Tour
Wind and lie randomness nudge shots
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
