Building comparison
head to head
AudiosurfvsHalf-Life 2
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Audiosurf
Execution · Pure Mechanics
A rhythm racer that turns any music file into a reflex puzzle track.
Half-Life 2
Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.
Audiosurf leans Execution (Pure Mechanics); Half-Life 2 leans Execution (Pure Mechanics).

Execution7 vs 6
Audiosurf leans a little harder on execution, though the gap is small.
Audiosurf
Lane-switching to the beat tests reaction speed.
Half-Life 2
Gravity gun and shooting demand precision.
Reads0 vs 1
Half-Life 2 leans a little harder on reads, though the gap is small.

Half-Life 2
Combine AI scripted, non-adaptive.
Variance2 vs 1
Audiosurf leans a little harder on variance, though the gap is small.
Audiosurf
Track generated from song, then fixed.
Half-Life 2
Almost no randomness.
Optimization4 vs 3
Audiosurf leans a little harder on optimization, though the gap is small.

Block-matching color strategy learnable per song.
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.
