head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.

Execution · Pure Mechanics
Light-gun aim speed against fixed enemy waves on Mario-themed rails.
Half-Life 2 leans Execution (Pure Mechanics); Yoshi's Safari leans Execution (Pure Mechanics).
Yoshi's Safari leans a little harder on execution, though the gap is small.
Half-Life 2
Gravity gun and shooting demand precision.
Yoshi's Safari
Super Scope aim speed and accuracy is the entire test
Half-Life 2 leans a little harder on reads, though the gap is small.
Half-Life 2
Combine AI scripted, non-adaptive.
Yoshi's Safari
Enemies attack on fixed choreography
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life 2
Almost no randomness.
Yoshi's Safari
Stages play identically every run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life 2
Linear progression with no builds.
Yoshi's Safari
Memorising boss weak points and wave order helps
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.
