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
An off-road racer testing vehicle control over rough terrain plus freeform route choice.

Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.
1nsane leans Execution (Pure Mechanics); Half-Life 2 leans Execution (Pure Mechanics).
1nsane leans a little harder on execution, though the gap is small.
1nsane
Wrestling physics-heavy trucks over terrain is the core skill
Half-Life 2
Gravity gun and shooting demand precision.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
1nsane
Multiplayer jostling exists but barely rewards prediction
Half-Life 2
Combine AI scripted, non-adaptive.
1nsane leans a little harder on variance, though the gap is small.
1nsane
Terrain deformation and pile-ups add run noise
Half-Life 2
Almost no randomness.
1nsane leans a little harder on optimization, though the gap is small.
1nsane
Line choice and checkpoint routing across open terrain matter
Half-Life 2
Linear progression with no builds.
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.
