Building comparison
head to head
Half-Life 2vsNo Thing
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.
Half-Life 2
Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.
No Thing
Execution · Pure Mechanics
A surreal auto-runner testing nothing but sustained split-second turn timing.
Half-Life 2 leans Execution (Pure Mechanics); No Thing leans Execution (Pure Mechanics).

Axis by axis
Execution6 vs 6
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life 2
Gravity gun and shooting demand precision.
No Thing
Split-second turn timing at speed is the entire game
Reads1 vs 0
Half-Life 2 leans a little harder on reads, though the gap is small.
Half-Life 2
Combine AI scripted, non-adaptive.
No Thing
No opponent, only the track
Variance1 vs 0
Half-Life 2 leans a little harder on variance, though the gap is small.
Half-Life 2
Almost no randomness.
No Thing
Courses are fixed and memorisable
Optimization3 vs 2
Half-Life 2 leans a little harder on optimization, though the gap is small.
Half-Life 2
Linear progression with no builds.
No Thing
Memorising turn sequences helps but reflexes still rule
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.
