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
Input precision across five fixed skateboarding events with learnable optimal lines.
Half-Life 2 leans Execution (Pure Mechanics); Skate or Die leans Execution (Pure Mechanics).
Skate or Die leans a little harder on execution, though the gap is small.
Half-Life 2
Gravity gun and shooting demand precision.
Skate or Die
Joystick precision on ramps, jumps and races decides every event
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life 2
Combine AI scripted, non-adaptive.
Skate or Die
Pool joust against another human adds slight prediction
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.
Skate or Die
Courses are fixed; nothing hidden after a few runs
Skate or Die leans a little harder on optimization, though the gap is small.
Half-Life 2
Linear progression with no builds.
Skate or Die
Learning each event's optimal lines and trick values raises scores
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.
