Building comparison
head to head
Half-Life 2vsVector
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Half-Life 2
Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.
Vector
Execution · Pure Mechanics
Timing parkour inputs through fixed chase levels with escalating precision.
Half-Life 2 leans Execution (Pure Mechanics); Vector leans Execution (Pure Mechanics).

Axis by axis
Execution6 vs 7
Vector leans a little harder on execution, though the gap is small.
Half-Life 2
Gravity gun and shooting demand precision.
Vector
Precise swipe timing on parkour tricks decides every chase
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.
Vector
The pursuing hunter is fully scripted
Variance1 vs 0
Half-Life 2 leans a little harder on variance, though the gap is small.
Half-Life 2
Almost no randomness.
Vector
Levels are fixed with nothing random
Optimization3 vs 3
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.
Vector
Learning trick placements per level maximises 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.
